About this gig

Are you looking for a smart AI chatbot that understands your business?

I will build you a custom AI chatbot or RAG (Retrieval-Augmented Generation) system using LangChain, Gemini API, and FAISS so your bot answers from YOUR documents and data.

What you get:

  • RAG pipeline trained on your PDFs or docs
  • Context-aware answers with conversation memory
  • Platform integration (Web, WhatsApp, Telegram, Slack)
  • Clean source code + README + setup support

Tech stack:

  • LangChain + FAISS + Gemini API / OpenAI GPT
  • Python + FastAPI or Streamlit
  • MongoDB for chat history

Perfect for:

  • Businesses wanting a support bot trained on their data
  • Startups needing an internal knowledge assistant
  • Developers wanting a production-ready AI backend

I am a CS student specializing in AI/ML with hands-on experience building RAG systems and LLM applications. Every project is built from scratch no templates.

Message me before ordering so I can recommend the right package for your needs.
