About this gig

Most AI chatbots are demos. They impress in the sales call, then hallucinate the moment a real customer asks a real question. I build the other kind chatbots that answer only from YOUR documents, cite 

their sources, and say "I don't know" instead of guessing.


I'm a senior AI & backend engineer with 12 years in production systems.


What you get:

A chatbot that answers from your content PDFs, docs, website, or knowledge base

Source citations on every answer, so your team can trust and verify it

Honest refusal when an answer isn't in your data, no confident nonsense

An accuracy report (Standard & Premium) measuring real retrieval quality before you sign off

Embeddable in one line, or deployed to your cloud


Why it holds up in production: I use hybrid retrieval keyword AND semantic search, so it catches exact codes and paraphrased questions alike. Every build is tested on your real questions, not a 

Happy-path demo.


Data cleanup, custom integrations, and hosting are separate add-ons quoted honestly up front.


Message me with your sources and top questions, and I'll tell you exactly what's possible.
