About this gig

Do you need to chat with your PDFs, documents, or internal knowledge base using AI?

I will build you a fully functional RAG (Retrieval Augmented Generation) chatbot that lets you upload your documents and ask questions in plain English. Built using LangChain, FAISS vector search, and a clean Streamlit interface.

What you get:

  • Document ingestion (PDF, TXT, DOCX)
  • FAISS vector store for fast semantic search
  • Multi-hop retrieval for accurate answers
  • Source citations so you know where each answer comes from
  • Clean Streamlit web interface
  • Full source code

I currently research LLM-based knowledge graph systems at AIMS-DTU and intern at WESEE, Indian Navy on applied AI. I build these systems daily.

Message me before ordering if you have specific requirements.
