Job Title: Computer Vision Expert for Custom Target Tracking Optimization
​Job Description:
I am looking for an expert in Computer Vision and Deep Learning to develop and train a high-precision object detection model (YOLO-based) specifically for Uncharted 4 Multiplayer.
​The goal is to create a professional-grade, stable tracking system with the following requirements:
​Adaptive Bounding Box: The system must maintain a stable tracking box restricted to the target’s upper body (from waist to head). This box must be adaptive; it must precisely adjust and scale according to the target's distance (e.g., focusing specifically on the head area for long-range targets).
​Target Exclusivity: The model must identify active human players only. It must be strictly trained to ignore:
​Map elements, static assets, and environmental clutter.
​Visual distractors like objective markers (e.g., the red 'King of the Hill' capture zone).
​Non-player objects that resemble human silhouettes, such as statues, posters, and paintings.
​High-Performance Training: I require a robust training process using:
​Data Augmentation: Incorporating various lighting conditions, motion blur, and occlusions (partially hidden targets).
​Negative Samples: Extensive training on "friendly" markers and background elements to ensure zero false-positive detections.
​Movement-Based Validation: The model should prioritize active human movement patterns over static shapes to avoid false triggers.
​Integration Readiness & Documentation:
​The final model must be stable, modular, and ready for integration into a Python-based control system.
​I require the code to be clean, well-commented, and accompanied by brief documentation on how to fine-tune the model for future adjustments.
​Latency Optimization: The model must be optimized for high frame rates (FPS) and minimum latency to ensure real-time responsiveness.
​Application Requirements:
Please highlight your experience with custom YOLO training, object tracking stability, and your approach to handling environmental noise in high-motion environments. If available, please provide a video demo or examples of your previous work in target tracking stability

I am looking for a Python developer with experience in physics simulation to create a simple script for a rigid-body variable sweep.

About us
We're Averon Advisory Partners, an AI automation agency that builds and integrates AI agents into recruitment agencies' existing systems. We take the admin that eats recruiters' days — resume screening, candidate sourcing, outreach, interview scheduling, inbox triage, ATS/CRM updates, compliance checks — and turn it into agentic workflows that run quietly in the background.
We're early-stage and moving fast. We work in tight 1–2 week build cycles and ship real, working automations into client environments rather than slide decks. We're looking for a contractor who can build at that pace with us.

What you'll be building
You'll own end-to-end automation builds across client engagements, including workflows like:

- Resume screening and shortlisting (with human-in-the-loop guardrails — no auto-rejects)
- Candidate sourcing and enrichment
- Personalised candidate/client outreach
- Interview scheduling and coordination
- Inbox triage and drafted replies
- Pre-screen Q&A flows
- ATS and CRM record updates
- Reference and compliance checks with audit logging

Our stack
We're tool-agnostic and pick what fits the client. Our primary stack is n8n for orchestration and the Anthropic Claude API for the reasoning layer, but we work across the wider ecosystem and want someone who's comfortable doing the same:

Orchestration: n8n (primary), plus Make, Zapier, Pipedream, or custom code (Python/Node) where it's the better fit

LLM APIs: Anthropic Claude (primary), plus OpenAI, Google Gemini, and others — including frameworks like LangChain / LlamaIndex where useful

Integrations: ATS/CRM platforms (Bullhorn, JobAdder, Vincere, etc.), email, calendars, and web data sources

Plumbing: REST APIs, webhooks, OAuth, vector stores/RAG where relevant, with a strong eye on reliability and clean error handling

You're a strong fit if you have:
- Hands-on experience building real, deployed automations in n8n and/or comparable platforms (Make, Zapier, Pipedream, or custom code)
- Solid experience with one or more LLM APIs — prompt design, structured outputs, tool/function calling; Claude experience is a plus but not required
- Comfort with REST APIs, webhooks, OAuth, and JSON wrangling
- A track record integrating with ATS/CRM or other SaaS platforms
- A bias toward shipping — you scope tightly, build, test, and hand off without hand-holding

Nice to have:
- Recruitment / staffing domain knowledge
- Experience with agent frameworks, RAG, or eval/testing patterns for LLM workflows
- Experience designing human-in-the-loop and audit-logging patterns
- Data-handling awareness around privacy (we operate under Australian Privacy Act obligations and treat compliance as non-negotiable)

Engagement
Project-based to start, with strong potential for ongoing work as our client base grows. Most builds run in 1–2 week sprints. Remote, async-friendly; we care about output, not hours logged.

Budget: $600 - $2,000+ AUD.
*This is an initial project. Successful candidates will have access to ongoing client implementation work.

How to apply
To keep this quick, please:

Start your proposal with the word "Shortlist" so I know you read this.

Share 1–2 specific automation workflows you've built — ideally something involving an LLM and an external integration. A short Loom walkthrough beats a paragraph.

Tell me, in 2–3 sentences, how you'd approach a resume-screening workflow that flags top candidates but never auto-rejects anyone.

I read every proposal that follows those three steps and reply fast.

We're a Long Island digital marketing agency that runs everything through GoHighLevel. We're looking for a developer who can extend GHL beyond what it does out of the box. This is custom integration and dev work, not basic workflow admin.

About Us

Design ME Marketing has been serving 200+ businesses since 2012. GHL is our operating system. We've already built out the standard stuff inside the platform. What we need now is someone who can connect GHL to tools that don't have native integrations, build custom dashboards on top of GHL data, and engineer workflows that go beyond drag-and-drop.

What We Need Help With

Custom API integrations between GHL and third-party tools that don't have native connectors. Pulling data in, pushing data out, and keeping things in sync.

Regular and Custom dashboards built on top of GHL data. Pulling from the GHL API to display reporting, metrics, client-facing views, and internal team views that GHL's native dashboards can't handle.

Webhook engineering. Custom endpoints (if needed)

Advanced workflow logic that requires external processing. Anything where GHL's native workflow builder hits a ceiling and we need a real script or service to do the heavy lifting.

Custom field manipulation, data transformation, and bulk operations across sub-accounts.

Who You Are

You EXCEL at all native GHL elements, specifically in the dashboard.

You will be told what elements need to be on the dashboard for reporting purposes, but will also want to lean on someone's expertise as well.

You've worked with the GHL API directly, not just the workflow builder. You can read API docs, write clean code, and build integrations that don't break the second something changes upstream. You're comfortable with at least one of: Node.js, Python, PHP. You know your way around webhooks, OAuth, and REST APIs. You can spin up a custom dashboard from scratch and deploy it somewhere stable.

Bonus points if you've worked with GHL's SaaS mode, built snapshots that include API integrations, or have experience syncing GHL with platforms like Airtable, Supabase, custom databases, or proprietary CRMs.

Project Details

This starts as project-based work with a strong shot at an ongoing retainer. We have a real backlog of integrations and custom builds queued up, and once we find someone solid we want to keep them busy.

To Apply

Tell me:

How long you've been working with the GHL API specifically, not just the GUI

Hello,
We came across your profile and noticed your experience with DIALux modeling and lighting calculations, which aligns very well with our current project requirements.
We are looking for a professional who can support us with the lighting design of an entire hotel floor. The scope of work includes:

- Creation of the 3D DIALux model based on the floor plan we will provide.
- Modeling of all interior spaces and common areas included in the project.
- Execution of lighting calculations and generation of the corresponding DIALux reports.
- Verification of compliance with the required lighting levels for the different environments.

Please note that we will define and provide the lighting fixtures (luminaires) to be used, so your focus will mainly be on the modeling, calculation, and documentation aspects.
We will also provide a floor plan to give a clear understanding of the layout and dimensions of the spaces involved.
If you are available and interested, we would be happy to discuss the project details, timeline, and deliverables.
We look forward to hearing from you.
Best regards,

## Overview

I am looking for an experienced iOS automation developer with strong Lua scripting skills to help complete an existing mobile automation project running on a dedicated iOS device.

The project is already started and the foundation is in place, but it is still far from production-ready. Approximately **40% of the system has been implemented** and I need someone who can continue development, fix existing issues, and complete the remaining functionality.

This is not a greenfield project. You will be working with an existing codebase and infrastructure.
