I will build a langchain chatbot or rag for fastapi or django

I will build a custom AI chatbot or RAG system for your FastAPI or Django application using LangChain and LangGraph.

I can help you add AI features to an existing Python backend or build a simple AI-powered solution from scratch.

Services I can provide:

• AI chatbot integration
• Retrieval-Augmented Generation (RAG)
• PDF and document-based question answering
• Vector database integration
• LangChain and LangGraph workflows
• OpenAI, Claude, Gemini, or other LLM integrations
• FastAPI or Django API integration
• Conversation memory and basic tool calling
• Clean, maintainable source code
• Setup documentation and guidance

Technologies may include LangChain, LangGraph, FastAPI, Django, OpenAI, Chroma, FAISS, pgvector, PostgreSQL, and other tools depending on your requirements.

Please contact me before ordering if you have custom requirements or an existing application that needs integration.
