I’m a senior Unity and C# developer who builds games, prototypes, tools, and real-time 3D applications. If you're working with me, you're getting accountability, creativity and technical excellence. I use a cutting edge modern Unity workflow combining years of experience, the Unity MCP plugin and flagship models from Anthropic, Cursor and OpenAI. You're paying for a seasoned veteran using the most effective tools who can look at any line in your code and explain to you in plain english what it does and why it does it.
What I can help with:
Unity Apps / C# game development
Gameplay systems, UI, tools, prototypes, production features, debugging, polish, optimization, and platform-specific fixes for PC, Android/iOS, WebGL and VR.
AI-enabled games and interactive systems
NPC dialogue, local model integration, procedural quests, AI-assisted content generation, narrative engines, runtime data pipelines, and practical AI features that fit inside an actual Unity project.
Backend and service integration
Databases, APIs, player/user data, analytics, multiplayer services, auth flows, admin tools, live content, and external hardware or device inputs.
Technical rescue work
I’m comfortable entering messy projects, finding the real problem, stabilizing the build, cleaning up broken systems, and giving the client a clear path forward.
Recent work in 2025-2026 has included Mobile and PC strategy, action and MMORPGS, custom Unity tools, AI-powered narrative/gameplay systems, WebGL and VR projects, Android/iOS app updates, ad/IAP integrations, hardware-input arcade experiences, realtime Windows companion apps, and large-scale experimental game prototypes.
If you’re serious about building something awesome, I’m happy to work hourly or by milestone depending on the shape of the project. Please get in touch!

I engineered the backend infrastructure for an Acquisition International AWARD-WINNING platform trusted by Fortune 100 companies. On Upwork I am TOP-RATED with a perfect 100% Job Success Score across every client I have worked with.
I am a senior AI engineer whose code is running right now inside companies you have definitely heard of. My record includes $25 MILLION in documented client savings.
I build RAG pipelines, full-stack SaaS platforms, and AI infrastructure that ships and scales.
I was the founding engineer of a legal-tech SaaS platform where I designed the entire architecture from scratch: multi-tenant PostgreSQL with row-level security, LangChain RAG pipeline with HNSW-indexed pgvector search, Claude and OpenAI API integration with Pydantic output contract enforcement, and a three-tier RBAC system. In legal-tech, a single hallucination can create client liability. I built the system so it could not happen.
I engineered the backend data infrastructure for LaborAI, recognized by Acquisition International as a Top Innovator in Labor Management Software in 2024 and trusted by Fortune 100 companies. I built the ingestion pipelines, idempotency controls, and query optimization layer that power real-time labor intelligence across thousands of warehouse touchpoints globally. My work reduced API latency by 40% and directly expanded the platform's throughput capacity.
I have contributed production-grade tooling to Composio, an open-source AI integration framework now used by engineers worldwide. My code ships inside other people's production systems.
✅ AI Systems: LangChain, LlamaIndex, CrewAI, RAG, OpenAI API, Claude API, Pydantic, multi-agent orchestration
✅ Backend: Python, FastAPI, Node.js, PHP, Laravel, REST APIs, GraphQL, OAuth, webhook integration, idempotency controls
✅ Frontend: React, Next.js, TypeScript, jQuery, Bootstrap, Tailwind, HTML5, CSS3
✅ Databases: PostgreSQL, MySQL, Redis, pgvector, relational schema design, query optimization
✅ Cloud: AWS, Docker, CI/CD pipelines, Vercel, Render, Cloudflare, Linux, nginx
I hold an AI certificate from Florida International University and have shipped systems across legal-tech, logistics intelligence, AI workflow automation, and cybersecurity visualization.
I work fast, communicate clearly, and build systems meant to last. If you need something deployed and working, not just demoed, let's talk.
