About this gig

I build AI chatbots powered by LangChain and RAG that answer questions from YOUR documents not generic AI responses.


What you get:

Document ingestion pipeline (PDF, DOCX, web pages, CSV)

Vector database setup (ChromaDB or Pinecone)

LangChain retrieval chain with OpenAI GPT-4

FastAPI backend with conversation memory

Deployed and ready to use


Perfect for:

Knowledge base Q&A (internal docs, HR policies, manuals)

Customer support chatbot (trained on your FAQ/docs)

Legal/medical document search

E-commerce product assistant

Research paper analysis


How it works:

1. You send me your documents

2. I build the ingestion + embedding pipeline

3. I create the retrieval chain with LangChain

4. I deploy a FastAPI endpoint you can integrate anywhere

5. You get accurate, sourced answers from your own data


Tech stack: Python, LangChain, ChromaDB, OpenAI, FastAPI, Docker
