I will integrate chatgpt or any llm API into your application
Full Stack AI Developer, Python, FastAPI and LLM Integration
About this Gig
Want to add AI to your app but not sure where to start? I will integrate ChatGPT, Claude, Llama, or any LLM API into your application cleanly and reliably using Python and FastAPI.
Whether you need a conversational AI feature, a document question answering system, or a backend endpoint that calls an LLM and returns structured responses, I will build it properly with clean, well-documented code you can maintain yourself.
What I can build: ChatGPT or OpenAI API integration, Claude or Llama setup, RAG pipelines that let your AI answer questions over your own documents, LLM-powered FastAPI endpoints, prompt engineering, and streaming response support.
I have built and deployed production LLM systems including an agentic buyer discovery system using Llama 3.1 and a full RAG pipeline evaluation framework with dual LLM judges. This is real production experience, not tutorial work.
What you receive: fully working integration code, clean commented implementation, a short explanation so your team can maintain it, and one revision if needed.
Let's add AI to your product the right way.
