Reverse Engineering Projects for Freelancers

I have a single Windows executable that was originally written in C++, but the working copy of the source code has been lost. The file is completely self-contained—no Boost, no custom DLLs, nothing to chase down—so the job is focused purely on reversing the compiled binary back into clean, human-readable C++.

Your objective is to produce well-structured code that can be rebuilt into an equivalent executable. I am comfortable with industry-standard reverse-engineering tools such as IDA Pro, Ghidra, Hopper, or RetDec, so feel free to choose the workflow you prefer, as long as the end result meets the criteria below.

Deliverables
• A C++ project that compiles on a recent MSVC or GCC/Clang toolchain and reproduces the original program’s behaviour
• Readable, logically named source and header files with inline comments explaining non-obvious logic or reconstructed data structures
• A short build/read-me outlining any compiler flags or environment settings required

I will test the code by compiling it on my machine and running a feature-by-feature comparison against the original EXE. Payment will be released once the rebuilt version matches the original in function and stability. If you have prior experience decompiling standalone Windows binaries and cleaning up the generated output, I look forward to working with you.

Skills: C Programming, C# Programming, Software Testing, C++ Programming, x86/x64 Assembler, Software Development, Binary Analysis, Reverse Engineering

I have several double-layer printed circuit board that has stopped performing reliably. Several symptoms point to multiple underlying faults: a few components no longer behave as expected, some traces appear open or damaged, and certain connectors intermittently lose continuity. Unfortunately, I do not have the original schematic or any Gerber/design files, so the job will require hands-on troubleshooting and a bit of reverse-engineering.

Here’s what I need from you:

• Locate and replace or re-solder the malfunctioning components.
• Identify and restore any broken or lifted traces so every signal path is solid.
• Resolve the intermittent connection issues at the board’s headers and edge connectors.
• Once the board is fully functional again, capture a simple schematic (even a clean hand-drawn or KiCad recreation is fine) so I have reference documentation for future work.

You should already be comfortable tracing double-layer boards with limited documentation, using tools such as a multimeter, oscilloscope, continuity tester, rework station, and—if available—a microscope for fine-pitch inspection. Please let me know how you typically verify repaired boards and what turnaround time you can offer once the board is on your bench.

Deliver a working board and the reference schematic; photos or brief notes describing each fix would be appreciated.

Skills: Electronics, CAD/CAM, Troubleshooting, Electrical Engineering, PCB Layout, Circuit Design, Circuit Board Layout, Embedded Systems, Prototyping, Reverse Engineering

Android MOBA that was built with Unity and is publicly available on Google Play. What I need is a clean client-side modification that unlocks all character skins locally (no server-side changes). The goal is to adjust only the visual layer so game balance and network traffic remain untouched; think of it as a skin-unlock toggle that the app reads from the device rather than the server.

You will be working from the retail .apk, so experience decompiling IL2CPP or Mono builds, analysing obfuscated assemblies with tools like dnSpy/Il2CppDumper/APKTool, and then repackaging a signed build is essential. If a lightweight in-app patcher or a separate injector is safer than distributing a full rebuilt apk, I’m open to that.

Deliverables
• Working proof-of-concept build (or patcher) that grants every character skin on the client, visible in matches and lobbies.
• Step-by-step instructions so I can reproduce the build or apply the patch after updates.
• Brief technical write-up explaining which classes, asset bundles, or addressable files were modified and why.

Acceptance criteria: launching the modified game on a non-rooted device should show MOST character skins as owned without tripping the game’s anti-cheat or causing disconnects.

If this is within your Unity reverse-engineering toolkit, let’s get started.

Skills: Mobile App Development, Android, Game Design, Technical Writing, C# Programming, Unity 3D, Software Development, Game Development, Reverse Engineering, Unity

I’m building a collectible/wearable charm bracelet concept. I’m looking for an experienced product designer / mechanical engineer to design a clean, continuous-loop bracelet band made from medical-grade silicone (or equivalent skin-safe wearable silicone) that fits most wrists via stretch-fit (no clasp, no adjustable mechanism).



The band must support 7 charm positions and an interchangeable charm interface where charms sit slightly raised and “pop in” with a satisfying feel. Retention should be secure during everyday wear (movement, light impacts, daily activity) while still being hand-swappable without tools.



I don’t have final measurements yet — I’m hiring you specifically to help define ideal sizing and geometry through an iterative prototype process. To protect IP, I will share only functional requirements at first; detailed interface constraints and any proprietary specifics will be shared after shortlist under NDA.



What I need you to deliver



1) Fit strategy + concept options



Recommend a “fits-most” sizing strategy for a continuous loop (and propose two sizes max only if truly necessary).



Provide 2–3 feasible interface concepts suitable for an elastomer band + removable charms.



Identify key risks and mitigation (tear risk, stress concentration, retention loosening, tolerance sensitivity).



2) Prototype-ready CAD



Parametric CAD for the band (and reference charm/interface) suitable for rapid iteration.



Deliver formats: native CAD + STEP, and STL if useful for prototyping.



3) Prototype plan + test method



Recommend the best prototyping path (soft tooling / casting / service bureau) and a silicone hardness range to test (Shore A guidance).



Provide a simple test checklist I can run for comfort, insertion/removal feel, retention security, and swap-cycle durability.



4) Final production-ready handoff



Final CAD package organized for manufacturing quotes: clean STEP files, key drawings/notes, DFM considerations, and any guidance a manufacturer will need.



What I will share at the start (safe info)



Brand/product intent (collectible bracelet + charm swapping)



“No clasp/adjuster” preference; clean loop aesthetic



Charm positions: 7; charms slightly raised



Performance priorities: secure retention first, but still easy hand swap



Reference imagery for style/vibe (no proprietary cross-sections)



What I will NOT share until shortlist + NDA



Exact retention/interface geometry or cross-sections



Final dimensions/tolerances



Any unique locking mechanism details



Full CAD/schematics of proprietary elements (if any exist yet)



Ideal freelancer



Proven experience with silicone/elastomer parts and consumer wearables



Experience designing secure-but-removable interfaces (press/snap fits appropriate for flexible materials)



Strong DFM thinking and clear CAD deliverables



Please include in your proposal



2–3 relevant examples (silicone/elastomer, wearables, modular inserts)



Your recommended approach and milestone plan



Estimated timeline and CAD tools you use



Production-ready requirement: Final delivery must be suitable to send to a manufacturer for quoting and tooling. Include STEP exports + native CAD, key 2D drawings with critical dimensions/tolerances, a short DFM summary (molding feasibility notes), a material/hardness recommendation (medical/skin-safe silicone), and a CTQ/QC checklist for production. Also include a simple test plan with suggested targets for swap-force/retention and cycle durability.



I have some sample images of what the charms could look like (style + general proportions). For this phase, I want you to design one functional test charm in this style (simple geometry is fine) so we can validate fit, retention security, and pop-in/pop-out feel with the silicone band.

We have a decimated STL (~200k triangles) of a historic building trim piece. The task involves reverse engineering this mesh into a clean STEP file, focusing on maintaining the original design intent and accuracy. The ideal candidate will have experience in architectural modeling and be able to deliver a precise and detailed model.

I have a box that I've designed in Shapr3D that I'd like recreated in freecad so it's easier to make different sizes of the box as needed for different uses. I enjoy working in Shapr3D but the model is not easy to resize. I don't know freecad well enough to model this yet, I'm working through some tutorials but I still have a ways to go.

I'm looking for someone who can recreate this box in Freecad while screen recording the process so I can learn from the recreation as well.

Hello!

I have forgot my Snap Chat My Eyes Only password - would you be able to help with that? The problem is if you reset the password it deletes everything in the account. I have valuable and sensitive photos in there that I need to recover with a gentle touch as these photos truly are for "MEO".
This would be amazing you could help!

Thank you for your consideration!

I have a working electronic product already selling in the United States, yet its current board is dated and hard to manufacture. I hold the original schematics but no PCB files, so the first step will be to extract every detail from the physical board, identify each component, and rebuild the entire design in KiCad.

Your primary objective is to reproduce all existing functionality while streamlining the layout for better design efficiency and smoother volume production. As you work, please keep U.S. safety, EMC, and environmental requirements in mind so the finished board is ready for certification. If firmware hooks or test pads reveal embedded code, document anything relevant that a firmware engineer would need to know; full‐scale firmware work is not expected, but component-level insight is.

Deliverables
• KiCad schematic and PCB layout files
• A clean, well-organized BOM with sourcing references for each component
• Gerbers, drill files, pick-and-place data, and any additional manufacturing outputs required by standard U.S. board houses
• A brief design report outlining key improvements you introduced for manufacturability and compliance

I will provide the product, high-resolution photos, and the legacy schematics as soon as we start. Let me know your estimated timeline and any clarifying questions so we can move forward quickly.

We're hiring a senior Agentic AI Engineer on a project-based contract to audit and harden our production personalization engine. You'll work directly with our Head of Product (Chris) and engineering team to take working prototypes to production-ready quality before November 2026.

This is a senior, project-based engagement (not full-time).

Estimated 30–60 hours per month, ~3 months, with the possibility of extension.

We're building a career-intelligence and upskilling platform serving learners across MENA and Africa. We deliver outcomes — completed cohorts, secured placements, career progression — for government training contracts, university partnerships, and large-employer partnerships.

What you'll do:
We've prototyped a personalization engine on top of our new Learn app. The basic framework exists to validate the concept; we want a senior engineer to make it production-grade. Specifically:

1. Architecture audit (Weeks 1–3)
Review the personalization engine end-to-end: - Zone 1 — Surfaces: homepage canvas, in-course chat, events / jobs / comms cards - Zone 2 — Agents: LangGraph supervisor + vertical agents (Courses, Events, Jobs, Comms) - Zone 3 — Backends: MongoDB Atlas vector store, course content + transcript ingestion, employer pipeline, PostHog telemetry - Zone 4 — Self-improvement loop: scoring agent → user.md → tuned routing

Output: written assessment of what's load-bearing, what scales, what needs to change before COP32 onboarding (~10K learners, Nov 2026).

2. RAG / retrieval design review (Weeks 2–5)
- Chunking strategy for video transcripts + Markdown lessons
- Hybrid retrieval (dense + sparse) recommendations
- Reranking strategy
- Per-user scope enforcement (no cross-tenant leakage)
- Multilingual retrieval — Arabic + English minimum; Arabic word-error-rate is real
- Vector store choice review — MongoDB Atlas today; pgvector under evaluation

3. Prompt + eval system (Weeks 4–8)
- Supervisor routing prompts
- Vertical-agent prompts (Courses, Jobs, Comms)
- Structured-output validation
- Regression eval set design + CI integration
- Failure-mode catalog

4. Cost discipline (Weeks 6–10)
- Per-feature + per-organization token budgets with enforcement (we bill at org level)
- Cache strategy (we already cache canvas cards by content version)
Multi-tier model routing — frontier (Sonnet / GPT-4o) for paid cohorts, mid-tier for general learners, cheap-tier or self-hosted for unverified
Anti-abuse limits — topical-relevance classification, per-user daily caps
Cost reporting to PostHog dashboard

Our current stack
- LLMs: OpenAI + Anthropic (multi-provider posture)
- Orchestration: LangChain.js + LangGraph (supervisor + sub-agent pattern)
- Vector store: MongoDB Atlas (pgvector swap under evaluation)
- Backend: Node.js, Express, BullMQ workers, MySQL (Aurora)
- Frontend: Next.js 15 App Router, React, Tailwind
- Eval / observability: PostHog (in-flight); LangSmith or Helicone under evaluation

What success looks like
After 3 months we should have:
- Architecture assessment
- Working RAG/retrieval pass with documented quality metrics on a fixture eval set
- Production-ready prompt + eval pipeline in CI
- Adaptive AI framework that will improve based on learners' interactions
- Scaffolding for evaluations / quality control
- Cost projection for ~10K learners with cap + cache + tier strategy locked

Who you are
Required: - Built production agentic systems before — not just chat wrappers around an LLM API - Strong production RAG experience — chunking, retrieval quality, eval discipline - Comfortable in JavaScript / TypeScript (Node + Next.js) - LangChain.js / LangGraph experience, or strong opinions on alternatives you can defend - Cost-aware — you've watched LLM bills explode and have systems-level opinions about budgets, caches, multi-tier routing - Able to teach — engineers on the team are learning; you'll be expected to pair, write, and explain
Strongly preferred: - Multilingual retrieval (especially Arabic) - Eval framework experience (LangSmith, Helicone, custom) - Vector store experience beyond Mongo (pgvector, Qdrant, Pinecone) - Worked on platforms (not just internal tools) — you've shipped to real users

Engagement details
Duration: ~3 months starting June 2026
Time commitment: project-scoped; estimate 30–60 hours per month
Rate: senior contractor; competitive, scoped per project
Location: anywhere — async-first
Communication: weekly sync with Chris; ad-hoc Slack with team

How to apply
Send a short note about a production agentic system you built or significantly improved

Looking for a maniacal, detail-oriented software engineer. I've built v1 of the platform; need the professional to make it v2. Company is growing extremely quickly + technology improvements are crucial to sustaining trajectory.

This will be a full-time position. We will begin with a paid work trial and if it works, it can be a FT role. Pay will be competitive with level of talent.

Expectations:
*Enjoy solving hard infrastructure problems. The application is in the nitty gritty of U.S. healthcare payments. Extremely high value, but very detail oriented.
*Looking for adventure, not work-life balance -- we work 6+ days a week. Challenge is big!
*Extremely self-motivated / directed

Qualified applicants will have a history of solving difficult technical problems and jumping two feet in to startups.

• Explain, with some detail, the hardest 3 technical problems you have solved. If at a company, link to their webpage.
• What experience do you have, if any, with U.S. healthcare?
• How do you choose which projects you want to work on? How many do you take on at one time?

We run high-volume Meta ad campaigns in the California Lemon Law space (legal lead generation), spending $60K-$100K+ a month. We're looking for a Creative Strategist who lives and breathes paid social creative and keeps our content pipeline full so our team is never recycling old posts.
This is NOT a video editing or design role. We have an editor and a social media manager. Your job is to feed them.
What you'll do:

Constantly research competitor and adjacent-industry ad libraries (Meta Ad Library, TikTok), social accounts, and DR campaigns. Stay on top of new hook styles, creative formats, caption trends, and what's working right now.
Bring fresh creative ideas and concepts, pitch them to the founder in Slack for approval.
Write scripts and creative briefs (hooks, angles, on-screen text, shot direction).
Use AI tools (Arcads, HeyGen, ElevenLabs, Canva, and others) to generate or spec creative.
Traffic the pipeline: hand video briefs to our editor, provide images to our social manager, supply approved creative to our ads manager. Make sure everyone always has work in their queue.
Keep everything organized and moving in Slack, in collaboration with the founder who approves direction.

You're a fit if you:

Think in direct response: the ad's only job is the click, the hook is everything, you test and kill fast.
Already spend time in ad libraries reverse-engineering what works.
Can turn a reference you found into a ready-to-produce script and brief.
Are organized enough to keep multiple people fed and on deadline.
Bonus: bilingual English/Spanish, experience in legal, insurance, or financial lead gen.

To apply: Send a short note telling us a) a recent ad you saw that you thought was brilliant and why it works, and b) one creative idea you'd test for a Lemon Law campaign. Skip the generic cover letter.
