About this gig

Need a smart chatbot that actually knows your business? I build custom AI chatbots powered by 

RAG (Retrieval-Augmented Generation) so your bot answers from YOUR documents, website, or data 

not just generic AI knowledge.


WHY CHOOSE ME?

  • 3+ years of Python & AI development experience
  • 10+ successful AI projects delivered
  • Master's in Business Intelligence & Analytics
  • Certified in LangChain & LangGraph


WHAT I BUILD:

-Document Q&A bots (PDF, Word, CSV, website)

-Customer support chatbots

-Internal knowledge base assistants

-Multi-turn conversation agents

-Chatbots with memory & tool use


TECH STACK:

Python | LangChain | LangGraph | OpenAI / GPT-4 | Pinecone / FAISS | FastAPI | Streamlit


HOW IT WORKS:

1. You tell me your use case and data sources

2. I build and test the chatbot

3. I deliver working code + deployment guide
