Python and Django developer specializing in REST APIs, FastAPI backends, and ChatGPT and OpenAI integrations, building web applications that go from idea to production without cutting corners.
Core stack: Django, FastAPI, DRF, PostgreSQL on the backend, React and Next.js on the frontend, OpenAI, LangChain, and Pinecone on the AI side.
Python and Django developer with 10+ years building REST APIs, SaaS backends, and ChatGPT-powered applications using OpenAI, FastAPI, and LangChain.
Most clients come to me for one of two things, they need a solid Django or FastAPI backend built properly, or they want to add AI features like ChatGPT, LLM pipelines, or automation into an existing product without it becoming a mess. I've done both enough times to know what works.
I take projects from idea to deployment. Clean API design, solid database work, third-party integrations, and AI built into real products, not demos.
Recent work:
โ Built a SaaS platform in Django + React serving 10K+ monthly users
โ Added a context-aware ChatGPT chatbot into an existing Django app using OpenAI and LangChain without rewriting the backend
โ Built a RAG pipeline with FastAPI + Pinecone that replaced a manual research workflow, saving the team hours every week
โฆ๏ธBackend: Django, FastAPI, DRF, Celery, REST API, PostgreSQL, Redis, JWT/OAuth
