About this gig

You have documents, a website, or a knowledge base. You need a chatbot that actually answers questions accurately, without making things up.


I build production-ready RAG systems using LangChain, ChromaDB or FAISS, and FastAPI. I have deployed these systems in a real ML engineering role, not just tutorials.


What you get:

- A working API endpoint you can plug into your app

- Vector database setup with your documents indexed

- Basic documentation so you can run it yourself

- One round of revisions to get the answers right


I have published IEEE research and built LLM customer support chatbots with Phi-2 and Gemini API. If you need a chatbot that reads your data and answers like a human, message me first and tell me what documents you have.
