Studio: Stupid Brain Interactive
Project: Original 3D Fighting Game — Working Title TBD
Genre: 3D Competitive Fighting Game
Engine: Unreal Engine 5
Development Stage: Pre-production / Playable Prototype
Initial Focus: Core Combat System, Two Playable Characters & One Test Arena
Multiplayer Goal: Competitive Online Play with Rollback Netcode
Hiring Type: Freelance / Milestone-Based Contracts

PROJECT OVERVIEW

Stupid Brain Interactive is looking for talented human developers and artists to help create an original 3D fighting game built around technical depth, stylish presentation, impactful combat, and competitive potential.

My vision is to combine the technical fighting mechanics and competitive intensity of Tekken, the movement, defensive options, and environmental possibilities of Dead or Alive 2 Hardcore, and the precision, martial-arts presentation, and grounded combat philosophy of Virtua Fighter.

I also want the cinematic super attacks and explosive visual punctuation of Street Fighter, adapted to a 3D fighting game with its own mechanics, personality, and identity.

The atmosphere should take inspiration from the grounded, gritty presentation of Tekken 4, while the visual direction should aim for a modern, stylish 3D fighting game aesthetic inspired by the Virtua Fighter series.

These are creative references, not a request to copy existing games. I want to build an original fighting game with its own characters, fighting styles, mechanics, arenas, and visual identity.

My goal is to create a tournament-worthy fighter that feels raw, responsive, stylish, and satisfying in the player's hands.

I want players to feel the weight of every strike, recognize the personality behind every fighter, and develop the skill needed to compete at a high level.

IMPORTANT: NO GENERATIVE AI

This project will be developed through human creativity and craftsmanship.

I do not want AI-generated code, character models, concept art, textures, animations, environments, sound effects, writing, or any other AI-generated game content.

All deliverables must be created by human contributors using conventional, non-generative development tools.

Unreal Engine 5, Blender, Maya, ZBrush, traditional keyframe animation, conventional procedural modeling, and other standard production tools are welcome when used without generative AI.

Applicants must disclose their production workflows and any third-party assets or dependencies. Generative AI must not be used to create or modify project deliverables. The default policy is a complete prohibition.

I am hiring people for their actual skills, creativity, technical knowledge, and ability to solve problems—not automated content generation.

1. GAMEPLAY PROGRAMMER — UNREAL ENGINE 5

The first priority is finding a programmer who can establish the technical foundation of the fighting game.

I need someone who understands the differences between a traditional 3D arena brawler and a competitive 3D fighting game. The combat must be designed around precise inputs, timing, movement, defensive options, hit detection, frame data, and competitive consistency.

Responsibilities

Establish the Unreal Engine 5 project architecture.

Build the initial playable character controller.

Implement movement relative to the opponent, including forward, backward, sidestepping, and turning.

Develop the foundational attack, defense, and hit-detection systems.

Create a framework for attack properties, startup, active frames, recovery, and hit advantage.

Implement hit reactions, launchers, knockdowns, and combo interactions.

Establish blocking, throws, counters, and other defensive mechanics as defined by the combat design.

Build a camera system appropriate for a competitive 3D fighter.

Integrate character animation, hit reactions, and visual effects.

Create a foundation for cinematic super attacks.

Design the architecture so additional characters can be introduced without rebuilding the combat system.

Evaluate and plan for online multiplayer with rollback netcode.

Maintain clean, organized, documented project files.

Required experience

Strong Unreal Engine 5 gameplay development experience.

C++ and/or Blueprints, with a clear explanation of the proposed architecture.

Experience with fighting game mechanics, animation integration, or action combat systems.

Understanding of frame-based combat, input buffering, hitboxes, hurtboxes, and attack recovery.

Knowledge of multiplayer synchronization and rollback networking.

Ability to communicate technical limitations and realistic development estimates.

Rollback netcode

Online competitive play is a major goal. Rollback netcode must be considered early rather than added as an afterthought.

The programmer should explain how they would approach input prediction, simulation state restoration, re-simulation, synchronization, and combat consistency in Unreal Engine 5.

I want a practical technical proposal before committing to a complete rollback implementation. Standard network replication alone is not sufficient evidence of rollback expertise.

2. 3D CHARACTER MODELER

I want original fighters with memorable silhouettes, expressive faces, distinctive outfits, and strong visual identities.

Every character should feel like an individual, not a generic fighting game model wearing a different costume.

Responsibilities

Create original 3D character models.

Produce clean topology suitable for deformation and gameplay animation.

Prepare UVs, materials, textures, and appropriate character shaders.

Collaborate with the animator on rigging and deformation requirements.

Prepare models for integration into Unreal Engine 5.

Create clothing and accessories that support the game's visual identity.

Help establish a consistent character art pipeline for future roster expansion.

Character presentation

I want fighters to look like people who have lived, trained, fought, and developed their own personalities.

Character details may include:

Distinctive hairstyles and facial features.

Original outfits with recognizable silhouettes.

Clothing that responds naturally to movement.

Visible bruising and superficial cuts during combat.

Battle-worn appearances where appropriate.

Outfit damage and torn clothing during intense encounters.

Clothing damage must remain tasteful and non-explicit. The goal is to communicate the intensity of a fight, not to sexualize injuries or rely on nudity.

3. CHARACTER ANIMATOR

Animation will be one of the defining elements of this project.

I want the game to feel raw and physical while maintaining the clarity and responsiveness necessary for a competitive fighting game.

Responsibilities

Create original idle stances, movement, attacks, blocks, dodges, throws, and hit reactions.

Develop character-specific martial arts animations.

Build combo transitions and launcher follow-ups.

Create cinematic animations for super attacks.

Collaborate with the programmer to ensure animations support gameplay timing and cancel rules.

Develop strong anticipation, impact, recoil, and recovery.

Support the implementation of dynamic smears and hand-authored impact frames.

Desired animation style

Dynamic smears: Hand-authored visual poses or smear frames that emphasize speed and acceleration.

Impact frames: Brief visual accents that emphasize powerful strikes without obscuring gameplay.

Afterimages: Selective motion trails that reinforce particularly fast attacks or movement.

Weight and recoil: Characters should visibly react to powerful hits, counters, throws, and knockdowns.

Distinct fighting styles: A boxer should not move like a karate practitioner, and a grappler should not feel like a kickboxer. Each fighter needs a recognizable rhythm and physical identity.

The objective is a stylish presentation built on excellent animation fundamentals, not flashy effects covering up weak combat.

4. ENVIRONMENT ARTIST

I want environments with atmosphere, personality, and opportunities for cinematic combat.

The visual direction should draw inspiration from the grounded, gritty atmosphere associated with Tekken 4 while remaining original to this project.

Responsibilities

Build an original test arena in Unreal Engine 5.

Create environment models, materials, textures, lighting, and set dressing.

Establish a consistent visual language across arenas.

Optimize environments for gameplay and performance.

Collaborate with the programmer on collision, arena boundaries, and potential environmental interactions.

Design spaces that communicate atmosphere without compromising fighter visibility.

Environmental concepts

Potential arena concepts include:

Urban rooftops and high-rise locations.

Underground fighting venues.

Industrial facilities.

Distinctive city environments.

Indoor arenas with strong lighting and architectural character.

One feature I would like to explore is cinematic stage transitions, such as a fighter being knocked through a window or sent from one level of a multistory building into another combat area.

This should be implemented as a controlled gameplay transition with appropriate camera work, animation, collision, and player control—not merely a cinematic that removes the player's agency.

5. COMBAT DESIGN — TECHNICAL, RESPONSIVE & COMPETITIVE

The core of this project is a proper 3D fighting game.

I want depth for competitive players without making the game unnecessarily difficult for newcomers to understand.

Core combat concepts

Frame-based attack properties.

High, mid, and low attacks where appropriate to the chosen system.

Standing and crouching defense.

Throws and throw defense.

Sidestepping and three-dimensional positioning.

Counter-hits and punish opportunities.

Launchers and air combos.

Knockdowns and wake-up situations.

Movement recovery and attack recovery.

Input buffering and responsive controls.

Character-specific move lists.

Balanced risk and reward.

The precise mechanics will be developed with the programmer and Creative Director. I want applicants to explain how they would structure these systems to support competitive play.

Cinematic super attacks

I want the excitement of Street Fighter-style supers without turning the entire game into a different genre.

Potential features include:

A super meter or other resource system.

Cinematic attacks with unique character presentation.

Powerful attacks that reward good timing and strategic resource use.

Distinctive camera work and impact effects.

Clear gameplay rules for startup, interruption, invulnerability, and recovery where applicable.

Supers must fit the underlying 3D combat system and preserve the importance of player skill.

6. DAMAGE PRESENTATION — BRUISES, CUTS & CLOTHING DAMAGE

I want damage to have a visible effect on the fighters without turning the game into a blood-heavy experience.

Desired features

Bruises that appear or become more noticeable during a fight.

Superficial cuts and battle-worn facial details.

Clothing that can become scuffed, torn, or damaged.

Controlled impact sparks when attacks connect.

Strong hit reactions and physical recoil.

Distinctive visual feedback for heavy attacks, counters, and supers.

The game will not rely on graphic blood or gore.

I am interested in stylized blood-like sparks or impact particles that reinforce the intensity of a strike without depicting graphic injury. The overall presentation should remain focused on martial arts, physicality, and competitive action.

The team should propose a practical approach to these effects, including performance considerations and how damage visuals will behave during multiplayer rollback.

7. TAG MODE — POTENTIAL FEATURE

I am interested in exploring a tag-team mode inspired by the concept of Tekken Tag Tournament.

This is an exciting possibility, but I want the foundation of the single-character fighting system to come first.

Potential tag features include:

Two-character teams.

Tagging between active and reserve fighters.

Tag-in attacks and combo extensions.

Character-specific team interactions.

Rules for reserve-character health and recovery.

Competitive balance considerations.

The programmer should explain how the initial combat architecture could accommodate tag functionality later without requiring a complete rewrite.

Tag mode is a planned feature to investigate after the core prototype is established, not an assumption that it must be completed in the first milestone.

8. VISUAL IDENTITY AND CHARACTER PERSONALITY

I want this game to have charisma.

Each fighter should feel like an individual with a distinctive attitude, fighting philosophy, movement style, and presence.

Character identity should be communicated through more than dialogue or costumes. It should come through their stance, movement, attacks, reactions, supers, and overall presentation.

The visual direction should balance:

The gritty atmosphere of Tekken 4.

The technical and martial arts presentation associated with Virtua Fighter.

The defensive and environmental possibilities of Dead or Alive 2 Hardcore.

The cinematic impact of Street Fighter supers.

An original art direction that belongs to this game.

These are reference points, not instructions to reproduce another game's assets or protected identity.

9. INITIAL DEVELOPMENT SCOPE

I do not expect a full commercial fighting game to be completed in the first milestone.

The initial objective is a polished, playable prototype that demonstrates the core combat philosophy.

Milestone 1 — Technical Foundation

Establish the Unreal Engine 5 project.

Implement basic character movement.

Establish the combat camera.

Build the foundational combat architecture.

Create a basic test arena using placeholders.

Present a technical proposal for rollback netcode.

Document the initial architecture and development risks.

Milestone 2 — Two-Character Combat Prototype

Implement two playable character setups.

Establish basic attacks, defense, hit detection, and damage.

Implement initial combos, hit reactions, and knockdowns.

Establish character facing and sidestepping.

Create a functional combat test environment.

Milestone 3 — Art and Animation Integration

Create the agreed original character models.

Integrate rigs and foundational animations.

Add dynamic smears and impact effects.

Establish initial bruising and clothing-damage presentation.

Refine the environment, lighting, and camera.

Milestone 4 — Competitive Systems and Polish

Refine frame-based combat behavior.

Evaluate and implement the approved rollback approach.

Test multiplayer under simulated latency and packet loss.

Tune character balance and combat responsiveness.

Improve performance, stability, and documentation.

Milestones can overlap where appropriate. Deliverables, costs, acceptance criteria, and deadlines must be agreed upon before each milestone begins.

10. WHAT I EXPECT FROM APPLICANTS

Please include the following in your proposal:

Which role are you applying for: programmer, character modeler, animator, environment artist, or a combination?

What experience do you have with Unreal Engine 5 and 3D fighting games?

Can you provide examples of work you personally created?

How would you approach building a competitive 3D fighter inspired by these reference games?

If you are a programmer, how would you implement frame-based combat and approach rollback netcode?

If you are an animator, can you demonstrate original combat animation, impact timing, and dynamic smears?

Please be honest about your strengths, limitations, and availability. I value clear communication and realistic planning over exaggerated promises.

FINAL STATEMENT

I am the Creative Director of this project, and my goal is to create a stylish, technically strong, competitive 3D fighting game with its own identity.

I want a game that feels raw in the player's hands, where every strike has weight, every character has charisma, and mastering the mechanics is genuinely rewarding.

I want to explore cinematic supers, expressive damage presentation, dynamic animation, environmental stage transitions, and eventually tag-team combat.

But the foundation must be right. Responsive gameplay, excellent animation, a solid technical architecture, and a consistent visual direction come first.

I am looking for people who take pride in their craft and want to build something original through collaboration, iteration, and human creativity.

No AI. No shortcuts. No generic assets. Just human talent building an ambitious, original fighting game.

Stupid Brain Interactive — Original Ideas. Human Craftsmanship. Competitive Ambition.

Studio: Stupid Brain Interactive (Building It)
Project Title: RoughHouse
Genre: 3D Action Brawler / Fighting Game
Engine: Unreal Engine 5
Project Type: Original IP inspired by Urban Reign
Hiring: Gameplay Programmer, 3D Character Modeler, Animator, and Environment Artist
Development Approach: Milestone-Based Freelance Collaboration

PROJECT OVERVIEW

Stupid Brain Interactive is seeking talented human developers and artists to help bring *RoughHouse* to life, an original 3D action brawler inspired by the combat mechanics, team-based fighting, and gritty street-fighting atmosphere of *Urban Reign*.

As the Creative Director, my vision is to create a game that captures the intensity and freedom of classic 3D brawlers while introducing its own identity through stylish presentation, expressive combat animation, impactful movement, and satisfying gameplay.

I want this game to be creative, visually striking, and genuinely fun to play. This is not a project where I want generic assets, automated content generation, or a basic fighting system thrown together just to make a prototype.

I want a team of skilled people who understand their craft and can work together to build something original.

IMPORTANT: NO GENERATIVE AI WILL BE USED ANYWHERE IN THIS PROJECT.

No AI-generated code, character models, concept art, textures, animations, environments, sound assets, or other creative content. All work must be created by human developers and artists using traditional artistic skills and conventional development tools.

Tools such as Unreal Engine 5, Blender, Maya, ZBrush, Substance 3D, and other standard non-generative development software are welcome. The requirement is that the actual creative and technical work is performed by people, not generated by AI.

THE INITIAL GOAL: TWO PLAYABLE CHARACTERS

The first stage of development will focus on **two playable characters**. Rather than attempting to build a massive roster immediately, I want to establish the game's visual identity, combat foundation, and overall gameplay feel with two characters that are fun to control and fight against.

These characters will serve as the foundation for future development.

The initial prototype should demonstrate:

- Two playable 3D characters with distinct fighting styles and personalities.
- Responsive movement, blocking, dodging, attacking, and hit reactions.
- Combo systems, launchers, juggling, knockdowns, and follow-up attacks.
- Weighty, satisfying impacts with clear visual and animation feedback.
- A camera system designed specifically for close-range 3D brawler combat.
- A test arena that supports movement, combat, and environmental interactions.
- A technical foundation that can be expanded with additional characters, arenas, and gameplay systems.

I am open to using temporary mannequins or simple placeholder assets during the earliest programming stage. However, the goal is to transition toward original, human-created character models and animations as development progresses.

POSITION 1: UNREAL ENGINE 5 GAMEPLAY PROGRAMMER

I need a programmer who can establish the technical foundation of the game in Unreal Engine 5.

This person should understand 3D fighting games, action brawlers, character movement, combat logic, animation integration, and multiplayer architecture.

Responsibilities

- Build the initial project structure and gameplay framework in UE5.
- Implement responsive character movement and combat controls.
- Create the foundation for attacks, combos, hit detection, hit reactions, blocking, dodging, launchers, and juggling.
- Develop the gameplay framework for two playable characters.
- Implement camera behavior suitable for a 3D arena brawler.
- Establish systems that allow future characters and combat mechanics to be added without rebuilding the entire project.
- Work closely with the animator and modeler to integrate original character assets.
- Develop a test arena that allows us to evaluate combat and movement.
- Establish a multiplayer architecture designed to support rollback netcode.
- Document the code and project structure so the work can be maintained and expanded by the team.

Required technical experience

- Unreal Engine 5 and strong gameplay programming experience.
- C++ and/or Blueprints, with the ability to explain the technical approach.
- Experience with character controllers, combat systems, animation systems, and multiplayer gameplay.
- Understanding of deterministic simulation, network synchronization, input prediction, and rollback correction.
- Experience with fighting games or action brawlers is strongly preferred.

Rollback netcode is a serious requirement I do not want multiplayer added as an afterthought. The programmer must evaluate how rollback can be implemented in UE5, explain the proposed architecture, identify technical limitations, and develop a practical plan before major combat systems are built.

Standard network replication alone is not the same as rollback netcode. I want someone who understands the difference and can explain how the system will handle predicted inputs, corrections, and replaying game states.

POSITION 2: 3D CHARACTER MODELER

I am looking for a human 3D artist who can create original, production-ready characters with a distinctive visual identity.

Responsibilities

- Model the initial two playable characters from original creative direction and references.
- Create clean topology suitable for deformation and gameplay animation.
- Produce appropriate UVs, materials, and textures.
- Prepare character models for rigging and animation.
- Collaborate with the programmer and animator to ensure the models work correctly in UE5.
- Create presentation-quality character assets without sacrificing practical game performance.

The art direction should be stylized, expressive, and visually memorable. I am not looking for generic realism or characters that look like mass-produced stock assets.

The characters should have personality, strong silhouettes, and a clear visual identity that can grow into an original game roster.

POSITION 3: CHARACTER ANIMATOR

Combat animation is one of the most important parts of this project.

I want the game to feel fast, forceful, expressive, and satisfying. The animation should communicate the weight of each strike while still allowing for stylish movement and exaggerated action.

Responsibilities

- Create original animations for the two initial playable characters.
- Develop idle stances, walking, running, attacks, blocks, dodges, hit reactions, knockdowns, recoveries, and other foundational movements.
- Create combo transitions, launchers, juggling attacks, and follow-up animations.
- Work with the programmer to integrate animation states, transitions, and gameplay timing.
- Develop impactful anticipation, follow-through, and recovery.
- Support a stylized combat presentation with strong silhouettes and readable movement.

Desired animation style

I want to explore techniques such as:

- Dynamic smears: Hand-created smear frames that emphasize extreme speed and motion.
- Afterimages: Stylized motion trails or character afterimages during selected attacks and movement.
- Impact frames: Brief, carefully timed visual accents that emphasize powerful strikes.
- Exaggerated poses: Strong silhouettes and expressive key poses that make attacks instantly readable.
- Hit-stop and screen feedback: Deliberate pauses, camera reactions, and other effects that make attacks feel impactful.
- **Speed lines and motion effects:** Tasteful effects that reinforce the action without cluttering the screen.

These techniques should serve the gameplay rather than become visual noise. I want an intentional artistic style that blends naturally with the 3D characters and environments.

All animation and visual artwork must be created by human artists. Effects may be implemented through conventional Unreal Engine materials, Niagara systems, hand-authored sprites, meshes, or other appropriate techniques.

POSITION 4: ENVIRONMENT ARTIST

I need an environment artist who can create original arenas that feel like believable, lived-in spaces for intense street fighting.

Responsibilities

- Create an original test arena for the initial prototype.
- Develop environmental assets, materials, textures, lighting, and set dressing.
- Establish a cohesive visual direction that complements the character designs.
- Optimize assets and scenes for performance in Unreal Engine 5.
- Collaborate with the programmer to support potential environmental interactions and arena transitions.
- Help establish a visual foundation that can expand into additional locations.

The environments should have personality. I want spaces that feel grounded in the world of the game while allowing the combat to remain the center of attention.

Future possibilities include destructible props, environmental attacks, wall interactions, and transitions between connected areas. These should be considered in the design, but their implementation will depend on scope and development priorities.

ART DIRECTION: STYLISH, EXPRESSIVE, AND ORIGINAL

I want RoughHouse to have its own identity.

The goal is a stylish 3D brawler with expressive animation, strong character designs, satisfying combat, and a presentation that makes every encounter feel exciting.

The visual direction should prioritize:

- Strong silhouettes and readable combat poses.

RESEARCH REQUIREMENT: STUDY URBAN REIGN

Applicants must be willing to study *Urban Reign* to understand the gameplay principles that make this project possible.

I am particularly interested in its close-range combat, target switching, multi-opponent encounters, combo opportunities, team-based fighting, and the relationship between movement, positioning, and attacks.

The purpose of this research is to understand what works mechanically and translate those principles into an original game.

This is not a request to copy Urban Reign's proprietary code, assets, characters, animations, or other protected content. I want to learn from its design and create our own systems, characters, presentation, and identity.

Please explain which aspects of Urban Reign you would study and how you would approach adapting those gameplay principles in Unreal Engine 5.

DEVELOPMENT PHASES

Phase 1 — Technical Foundation
- Establish the UE5 project structure.
- Implement basic character movement and camera behavior.
- Build a functional combat test using placeholder characters.
- Establish the technical direction for future rollback networking.
- Define how the different development roles will collaborate.

Phase 2 — Two-Character Prototype
- Integrate the first two original character models.
- Implement core combat mechanics and animation states.
- Establish the initial visual style and combat feedback.
- Create the first playable test arena.
- Test movement, combos, hit reactions, and overall game feel.

Phase 3 — Combat Polish and Multiplayer
- Refine combat responsiveness, timing, and animation transitions.
- Implement and validate rollback networking according to the agreed technical plan.
- Test multiplayer synchronization under simulated network latency and packet loss.
- Refine visual effects, impact feedback, and performance.
- Document remaining technical limitations and future development needs.

The exact scope and milestone deliverables will be agreed upon before work begins. Each phase should have a demonstrable result that can be reviewed before the next milestone is funded.

STRICT NO-AI POLICY

This requirement is non-negotiable.

- No AI-generated source code or AI-generated code snippets.
- No generative AI for character models, concept art, textures, materials, or environment assets.
- No AI-generated animations, motion assets, or visual effects artwork.
- No AI-generated writing, design documents, dialogue, or other creative deliverables.
- No AI-generated audio or other game content.
- No AI tools used to produce, modify, or complete project deliverables.

Conventional software, procedural modeling techniques, standard rendering tools, traditional rigging tools, and non-generative automation may be used when appropriate. Any tool that incorporates generative AI into the creation or modification of deliverables must be disclosed and approved before use. The default is that generative AI is prohibited.

Applicants must be prepared to explain their workflow and confirm that their submitted work is their own human-created work. Work must be original or properly licensed, and all third-party assets must be disclosed.

I want to hire people for their skills, craftsmanship, problem-solving, and creativity. I am investing in human talent, not AI-generated shortcuts.

WHAT TO INCLUDE IN YOUR APPLICATION

Please answer the following when applying:

1. Which role are you applying for: gameplay programmer, 3D character modeler, animator, environment artist, or a combination?

2. What experience do you have with Unreal Engine 5 or similar 3D fighting games and action brawlers?

3. Can you provide examples of relevant work you personally created?

4. How would you approach building a two-character prototype inspired by Urban Reign?

5. If applying as a programmer, how would you approach rollback netcode in UE5, and what technical challenges do you anticipate?

6. If applying as an animator, can you create stylized combat animation, dynamic smears, and hand-authored impact effects?

7. Can you confirm that your work on this project will comply with the no-generative-AI policy?

8. What would you recommend as the first milestone, and what would you deliver within it?

Please be transparent about your availability, estimated costs, and the work you can realistically deliver.

FINAL NOTE

I am the Creative Director of this project, and I want to build a team that takes pride in making games.

I am not expecting one person to do everything. I want capable specialists who can collaborate, communicate, and help establish a solid foundation for something bigger.

The initial focus is two playable characters, a functional combat prototype, a distinctive visual style, and a technical architecture that can support future expansion.

If you are passionate about game development, understand the craft behind a great brawler, and want to create something original through entirely human work, I would like to hear from you.

No AI. No shortcuts. Human creativity, original work, and a game built with intention.

I have a single-purpose task in mind: I need a Python program that takes any standard MIDI file, shifts every note up or down by a user-defined number of semitones and, if requested, swaps one General MIDI instrument patch for another across the whole file. The transposition and the instrument swap should apply to every track and event so there is no need to filter by channel, time range, or track ID—one clean pass over the entire file is perfect for my workflow.

Command-line usage is preferred: something like
python midi_modifier.py input.mid output.mid --transpose +3 --replace 0 41
where transpose can be positive or negative and replace takes the original patch number followed by the new one. I am comfortable installing standard libraries, so feel free to rely on mido, pretty_midi, or any other well-maintained MIDI package available on PyPI. Please avoid heavyweight GUI frameworks; a concise CLI is all I need.

Acceptance will be based on: the script running from the terminal without errors, producing a valid MIDI that opens correctly in any DAW, and the transposition / instrument change reflecting the parameters passed.

Deliverables:
• The Python script with inline comments
• A brief README or usage note explaining required dependencies and example commands

Skills: C Programming, Python, Software Architecture, C++ Programming, Software Development, Scripting, Audio Processing, MIDI

I need a reliable player who can jump into my web-browser “horde survival” game for several hours each day while I’m on vacation. Each session is a simple 30-minute run: move around the map, collect the chests that drop, open rifts, clear the mini-bosses, and when the in-game timer hits 30:00 you exit and immediately queue up the next run. No grinding for the final boss, no side quests, no account tinkering—just the same safe routine run after run.

If a disconnect, patch, or failed attempt pops up, simply restart the game and resume the loop. The role is perfect if you’re already at your computer and want a light, steady task that earns a small passive income of roughly €2–3 per hour.

All you need is a stable internet connection and a desktop or laptop browser; no installs or extra software required. Consistent uptime and sticking to the run-only focus are the key success metrics. Let me know your usual daily availability, and I’ll share the account details so you can start farming.

We are looking for an experienced computer-vision engineer to develop a proof-of-concept system for virtual advertising in recorded football broadcast footage.

The initial prototype should replace advertising shown on physical LED perimeter boards with new supplied creative, while keeping the replacement correctly positioned as the broadcast camera moves.

This is an early-stage technical feasibility project. The first version will work with recorded footage rather than a live broadcast feed but we eventually want to get to that.

Initial prototype requirements

Using a short sample of football broadcast footage, the system should:

Identify and track the visible LED perimeter boards.
Replace the existing board content with supplied video or animated graphics.
Maintain correct scale, perspective and positioning during camera movement.
Mask players, officials and other foreground objects when they pass in front of the advertising.
Produce a clean exported 1080p video.
Use automated or semi-automated computer vision rather than manual frame-by-frame editing.
Be capable of being adapted to additional footage and stadium configurations.

The successful freelancer must provide the complete source code, documentation and setup instructions.

Required experience

Applicants should have strong practical experience in several of the following areas:

OpenCV
Python and/or C++
PyTorch, TensorFlow or similar frameworks
Camera calibration
Homography and perspective transformation
Semantic or instance segmentation
Object detection and tracking
Video compositing
FFmpeg or GStreamer
CUDA or GPU optimisation
Real-time or near-real-time video processing

Experience with broadcast graphics, augmented reality, virtual production, sports analytics, Unreal Engine, NDI or SDI workflows would be useful but is not essential.

Initial deliverable

The first paid milestone will involve approximately 30–60 seconds of supplied football footage.

The expected deliverable is:

Replacement of the visible LED advertising.
Stable tracking during camera pan, tilt and zoom.
Foreground masking when players cross the advertising area.
An exported demonstration video.
Complete source code.
Instructions explaining how to run the system with replacement creative.

This is not a video-editing or manual rotoscoping project. We are looking for a technically reusable computer-vision solution.

Potential future work

If the prototype is successful, further work may include:

Longer football broadcasts.
Automated stadium and board calibration.
Virtual 3D advertising carpets.
Support for different stadiums and camera positions.
An operator interface.
GPU optimisation.
Near-live or live video processing.
Multiple regional advertising outputs.

There is potential for a longer-term technical relationship for the right person or team.

Application questions

Please answer the following questions in your proposal:

Describe a relevant project where you anchored graphics or virtual objects to footage from a moving camera.
How would you track the geometry of LED perimeter boards during camera movement?
How would you mask players passing in front of the replacement advertising?
Would you use classical computer vision, machine learning or a combination of both?
How would you minimise manual calibration or rotoscoping?
What processing speed would you expect to achieve at 1080p?
What additional development would be required to make the system operate live?
Which parts of your previous work can you demonstrate on a video call?
Are you personally completing the work, or would any part be subcontracted?

Generic AI proposals will not be considered. Please explain your proposed technical approach and include examples of directly relevant work.

Commercial terms

The project will be structured through fixed-price milestones.

The client must receive:

Ownership of all bespoke source code following payment.
Access to the code throughout development through a client-controlled repository.
A list of all third-party libraries, models and licences.
Full disclosure of any existing proprietary components.
Documentation sufficient for another engineer to run and review the system.

The supplied footage and commercial information must remain confidential and may not be used in portfolios or demonstrations without written permission.

Please include:

Your proposed budget for the initial prototype and full development.
Estimated delivery schedule.
Recommended technology stack.
Any assumptions or technical limitations.

We need an experienced developer to integrate a volatility filter into an existing MT5 trading system. The work includes reviewing the current setup, implementing the filter logic, testing performance, and ensuring the system runs reliably in live or demo environments. You should be able to communicate clearly, follow project requirements, and deliver a stable solution within the agreed timeline. Experience with similar trading system enhancements is highly preferred.

I'm looking to develop LPR and/or Video Analytics, preferably in C++. I'm looking for someone with hands-on experience who has already developed these kinds of apps. I'm looking for actual application functionality, not just object detection models.
Please send me a demo if you have any.
Please start your msg with the words "I have experience with LPR / Video Analytics!"

I need a custom virtual camera that can join a Zoom call and replace my face in real time with a chosen subject’s face. Before each meeting I want to load one or more reference photos (or short video clips) of that person; once the call starts, the software should track my head and mouth movements and render a realistic, latency-free face swap that other participants see as my camera feed.

Zoom is the first platform I must support, but I eventually want to point the same virtual camera at Google Meet and Microsoft Teams, so please keep cross-platform thinking in mind. Whatever stack you prefer—OpenCV, MediaPipe, TensorFlow, Unreal’s LiveLink, or your own pipeline—you’ll need to handle live video I/O, facial-landmark tracking, texture blending, and create a signed driver or plugin so the operating system recognises the feed as a standard webcam.

Deliverables
• Desktop application (Windows or macOS) that appears in Zoom as a selectable camera
• Interface to import photos or videos that train/drive the swap model on the fly
• Real-time, high-resolution face replacement that matches lighting and expressions
• Installation package and brief usage guide for non-technical users

When you reply, just show examples of past work that prove you have already built—or heavily contributed to—similar real-time video or AR projects. A short demo clip or repo link is perfect.

Skills: C Programming, C# Programming, C++ Programming, OpenGL, Augmented Reality, Artificial Intelligence, OpenCV, Tensorflow, Computer Vision, Facial Recognition

I’m battling a persistent “Error 4004” that crashes my desktop application/game. The source code is available, the error is consistently reproducible on Windows, and I need a clean, permanent fix—not a workaround—delivered within one month of project start.

Please dive into the codebase, trace the exact trigger for Error 4004, patch it, and confirm stability across at least two system configurations. Share a concise summary of the root cause and the changes you make so I can maintain the project confidently going forward.

When you place your bid, include examples of past work where you successfully debugged and resolved similar desktop-software or game-related errors; that track record will weigh heavily in my decision.

Deliverables (all required):
• Repaired source (or diff/patch) eliminating Error 4004
• A brief technical report: root cause, steps taken, testing performed
• Compiled build or installer for quick validation

Everything must be turned around inside the one-month window. I’ll test, confirm, and release payment once the fix proves stable.

Skills: Windows Desktop, C# Programming, Software Architecture, Software Testing, C++ Programming, Debugging, Software Development

I need an end-to-end computer-vision pipeline that spots every Choy Sum plant in my greenhouse, decides whether it is Immature, Mature, or Overmature, pinpoints its X-Y-Z position, and flags only the harvest-ready plants for a robotic arm.

Camera & environment
• A stereo camera will be mounted above the crop beds; depth or single-lens alternatives are not planned at this stage.
• All images will come from my indoor farm, but none are yet captured or annotated, so the project starts with data acquisition and labelling.

Core objectives
• Train a YOLO-based detector in PyTorch that recognises individual plants and assigns the three growth-stage classes with high precision.
• Derive 3-D coordinates from the stereo pair, fuse them with the class prediction, and output a clean list of mature-plant positions.
• Package the results in a straightforward API or message format that my harvesting robot can consume.

What I expect to receive
- A documented data-collection protocol plus labelled dataset.
- All training scripts, inference code, and trained weights.
- A short technical report covering model architecture, evaluation metrics, and integration instructions.
- A live demo (video or remote session) that shows the system detecting, classifying, and localising plants in real greenhouse footage.

Please reply with your proposed timeline, a brief outline of your approach to stereo depth and YOLO fine-tuning, and any previous work you have done on agricultural vision systems or 3-D localisation.

Skills: C Programming, Python, Software Architecture, C++ Programming, Artificial Intelligence, Pytorch, Computer Vision, YOLO

I need a professional 3D artist to create the final, game-ready avatar assets for Tramo, an Android cycling app. Each user has a 3D human cyclist that levels up and can equip clothing, gear and bikes. The avatar is rendered in real time on mid-range phones by our own C++ engine (OpenGL ES 3.0), so all assets must be clean and optimized.

Style: we like stylized hero characters with hand-painted textures, similar to MOBA games. These two models show the level and feel we are looking for:
- https://sketchfab.com/3d-models/none-e285df46a7c640bf9d5eeb1454ab8a4b
- https://sketchfab.com/3d-models/none-f30e97934b9047fd9971ed022843efb4
These are only style references: our characters are modern human cyclists, not fantasy. We are open to your proposals. No third-party brands or logos, only our logo (SVG provided).

Scope:
- 2 base bodies (male and female): bare skin, minimal underwear, barefoot, short hair. Same skeleton with Mixamo-compatible bone names, A-pose, good deformation. Around 20-25k triangles per body, plus a lighter LOD.
- About 26 modular clothing items (cycling jerseys, bib shorts, gloves, cycling shoes, casual items), each fitted to BOTH bodies and skinned to the same skeleton. They must combine without clipping or gaps at waist, wrists and ankles. Around 3-8k triangles each.
- Rigid accessories: about 7 helmets, 3 sunglasses and a watch, attached to the head or wrist bone and fitting both bodies.
- About 5 bikes (city, fixie and road bikes), in the same style and scale as the character. The cyclist stands next to the bike, not riding it. Avoid thin wire spokes: use solid or deep-section wheels that read well on a phone screen. Around 10-15k triangles per bike.
- Budget for the full dressed character (body + clothing + accessories): max 50-60k triangles, plus the bike. If you think a different split works better, tell us in your proposal.
- Optional, quoted separately: a few poses and gestures on the same skeleton, and 3 trophies.

Technical: .glb (glTF 2.0), one file per body, one per clothing item per body, and one per accessory and bike. Hand-painted or PBR textures: 2048 px for bodies, 1024 px for clothing, accessories and bikes. Clean UVs and normals, real-world scale, Y-up. Names in English. Source files (.blend) included.

Milestones: first both bodies plus one complete outfit and one bike, which we test in our engine before continuing; then the rest of the clothing; then accessories and bikes. Full commercial rights transfer, 100% original work.

To apply: portfolio with game-ready characters (ideally stylized and with swappable clothing), experience with glTF and Mixamo rigs, how you would adapt this style to a modern cyclist (with examples of your own work), and price and timeline per milestone. Start your proposal with the word "pedal".

We are looking for an experienced Mechanical Engineer with strong embedded firmware development skills to help design and develop a smart electromechanical product from concept to functional prototype.

The project involves developing a compact automated device that integrates mechanical components, electric motors, sensors, and a microcontroller-based control system.

We need a hands-on engineer who understands both mechanical design and embedded firmware development and can take responsibility for integrating these systems into a reliable, functional product.

This is a real product development project, not a research or theoretical design assignment.

Project Responsibilities:

- Design and develop mechanical components, assemblies, and enclosures using SolidWorks, Fusion 360, or similar CAD software.
- Design and integrate motor-driven mechanical mechanisms, including gears, actuators, and moving assemblies.
- Select and integrate appropriate motors, sensors, microcontrollers, and electronic components.
- Develop embedded firmware using C/C++ for STM32, ESP32, or similar microcontroller platforms.
- Implement motor control, sensor interfacing, and automated operating sequences.
- Develop and troubleshoot communication interfaces such as I2C, SPI, UART, and PWM.
- Integrate mechanical, electrical, and firmware components into a complete functional system.
- Support prototype development, testing, troubleshooting, and design improvements.
- Prepare mechanical CAD files, firmware source code, technical documentation, and component specifications.

Required Qualifications:

- Strong professional experience in mechanical engineering and product design.
- Proven experience developing embedded firmware for microcontroller-based products.
- Proficiency in SolidWorks, Fusion 360, or equivalent mechanical CAD tools.
- Strong programming skills in Embedded C/C++.
- Experience with STM32, ESP32, Arduino, or similar microcontroller platforms.
- Practical experience with motors, sensors, actuators, and electromechanical systems.
- Good understanding of electronic circuits, wiring, and hardware integration.
- Experience developing functional prototypes involving both mechanical and electronic components.
- Strong troubleshooting and problem-solving skills.

Preferred Qualifications:

- Experience developing commercial electromechanical products.
- Familiarity with PCB design and electronic hardware development.
- Experience with motor drivers, PID control, and real-time embedded systems.
- Knowledge of 3D printing, CNC machining, and design for manufacturing (DFM).
- Experience preparing products for manufacturing and assembly.

Project Expectations:

We are looking for an engineer who can contribute to both mechanical design and embedded firmware development rather than specializing exclusively in one area.

You should be comfortable working independently, identifying technical challenges, proposing practical solutions, and communicating progress clearly.

The ideal candidate has previously developed complete electromechanical products and understands how mechanical systems, electronics, and firmware interact in real-world applications.

When Applying, Please Include:

1. A brief description of your mechanical engineering and embedded firmware experience.
2. Examples of previous products or prototypes involving motors, sensors, and microcontrollers.
3. The CAD software and microcontroller platforms you have worked with.
4. Your experience integrating mechanical systems with embedded firmware.
5. Your availability and estimated weekly working hours.

Please apply only if you have substantial hands-on experience in BOTH mechanical engineering and embedded firmware development.

We are interested in establishing a long-term working relationship with the right engineer as the product progresses through prototyping, testing, and further development.

I’m developing an AI-powered loss-prevention system for delis and convenience stores.

I own a deli in Brooklyn, NY, and want to build an MVP using our existing security cameras. The goal is to use computer vision to identify potentially suspicious activities involving cashiers and customers, such as unusual register activity, potential employee theft, and shoplifting.

The system should ideally:

* Connect to existing IP cameras and DVR/NVR systems using RTSP or ONVIF where supported.
* Analyze video footage using AI.
* Detect and flag specific suspicious events.
* Save short video clips with timestamps for review.
* Provide a simple dashboard and alerts for business owners.
* Eventually support multiple cameras and multiple business locations.

I’m looking for an experienced computer vision engineer with a background in CCTV, real-time video analytics, and AI surveillance systems.

I want to start with a small technical feasibility project using my own store’s cameras before investing in a full commercial platform.

I’m interested in your recommended technical approach, estimated timeline, and budget for an initial MVP.

The goal is to build a reliable, scalable product that can eventually be offered to other small businesses through a monthly subscription.

We are seeking an expert to design and develop a broadband Mimo Mesh SDR-Based Radio using the AD9361 series platform. The project includes implementing hopping and Ad hoc features to support dynamic network communication. The ideal freelancer should have strong experience in wireless communication systems and be able to deliver a reliable, high-performance solution. Please share relevant experience and examples of similar projects.

You will build agent environments from the real operating records of US businesses: dealerships, logistics firms, service companies. Most environments are built on invented tasks. Ours start from real work with real outcomes, such as a repair order, what the technician actually found, and whether the car came back.

Vellum licenses de-identified business records on behalf of the companies that create them. You would be our first engineer dedicated to turning those records into sandboxes, tasks and graders that AI developers train and evaluate agents on.
