I will build a custom rag ai chatbot and ai agents with langchain and python


About this gig
Looking for more than a simple ChatGPT wrapper?
I build production-style AI systems that connect Large Language Models to your private data so your chatbot answers from your documents, not from guesses. Using RAG (Retrieval-Augmented Generation), LangChain, LlamaIndex, and Python, I build context-aware systems with source citations and no hallucinations.
What I build for you:
Custom RAG chatbots chat with your PDFs, SQL databases, or live web data
Autonomous AI agents multi-agent workflows (LangGraph, CrewAI) that automate multi-step tasks
APIs & deployment FastAPI/Flask backends deployed on Azure, Railway, or Hugging Face
Clean, documented code commented source code you actually own
A real example of my work:
I built Scholar Agent, an autonomous agent that orchestrates 4 tools to answer research questions with cited sources shipped with testing, CI/CD, and Docker. https://huggingface.co/spaces/ms732/ScholarAgent
Why work with me:
I ship working software, not demos tested, documented, and deployed
Free scoping not sure what you need? Message me and I'll map it out at no cost
Let's build a system that doesn't just "chat" it actually works.

FAQ
Will the chatbot use my own data/documents?
Yes. That's the whole point of RAG — your bot answers from your PDFs, databases, or website, with source citations.
