I build custom RAG chatbots that answer questions directly from your PDFs, documents, and knowledge base using Python and LangChain.

What you get:

PDF and document upload with parsing

RAG pipeline with ChromaDB or FAISS vector search

Context-aware Q&A with source citations

Clean chat interface (Streamlit or FastAPI)

Your choice of LLM (OpenAI, Groq, or open-source)

Clean, documented, ready-to-use source code

Perfect for businesses wanting to chat with their documents, startups building AI support chatbots, and developers needing a production RAG system.

Message me to discuss your requirements.
