About this gig

Your team wastes hours digging through documents for answers that already exist.

I build custom AI chatbots that read your documents and answer questions instantly, with citations to the source so you can trust every answer.


What you get:

  • Chatbot trained on YOUR docs (PDF, Word, Excel, web, databases)
  • Accurate answers with source citations, not hallucinations
  • Clean chat interface, ready to use or embed
  • Deployed and working, plus full source code


Why me:

I'm a full-time AI Engineer building production LLM systems on AWS. I've delivered RAG systems for clients in legal, healthcare, finance and e-commerce.

Most "AI chatbot" gigs are a thin wrapper around ChatGPT. I build proper retrieval: smart chunking, hybrid search, reranking, and evaluation so you know it actually works.


Common uses: internal knowledge assistants, customer support, policy and compliance Q&A, research and onboarding helpers.


Tech: Python, LangChain/LangGraph, OpenAI/Claude, vector databases, AWS.


Please message me before ordering with what you need and I'll tell you honestly if this fits and which package suits.
