About this gig

Need an AI application that actually ships? I develop production-ready AI apps powered by OpenAI (GPT), Google Gemini, and custom/fine-tuned models from first prompt to deployed product.


What I deliver:

  • AI chatbots, assistants & autonomous agents (LangChain / LangGraph)
  • OpenAI & Gemini API integration into your web or mobile app
  • Custom AI model integration, fine-tuning & RAG pipelines
  • Full-stack builds: FastAPI · Next.js · React · PostgreSQL · AWS
  • Voice AI, document Q&A, and workflow automation


Why work with me:

  • 6+ years shipping production systems across fintech, healthcare & voice AI
  • Clean, scalable, documented code real products, not throwaway demos
  • Clear communication and on-time delivery


Whether you need a fast MVP or a scalable AI product, I'll help you pick the right model and build something that works in the real world.
