I will build your ai powered fastapi backend with llm integration
Sofiia Yankina
About this gig
Do you need a reliable AI-powered backend that works in production not just a demo?
I build Python backends with FastAPI and integrate LLMs (OpenAI, Claude, open-source models) into real applications. From simple API endpoints to full RAG pipelines with vector search I cover the full backend layer.
What you get:
- FastAPI backend with clean architecture and async support
- LLM integration with prompt engineering and structured outputs
- RAG pipelines using Pinecone, ChromaDB, or pgvector
- JWT auth, error handling, logging, Docker setup
- Full source code + basic documentation
Delivered ~5 commercial projects: AI customer support bots, document Q&A systems, automated content pipelines.
Message me before ordering I'll confirm the scope fits your needs and suggest the right package.
