About this gig

I will build a smart AI chatbot for your website or business using LangChain and RAG (retrieval-augmented generation), so it answers from YOUR documents, FAQs, or knowledge base not made-up answers.

What you get:

- A chatbot that answers from your own data (PDFs, docs, website content)

- Clean, working Python code you own

- Simple setup instructions

- Tested before delivery


I am a Software Engineer (AIML) with hands-on experience in LangChain, LangGraph, FastAPI, and LLM systems. I build practical, working solutions and deliver on time.
