About this gig

Looking to add AI to your business? I build custom chatbots and AI-powered tools using Gemini or GPT, tailored to your actual needs not a generic template.


What I do:


  • Build a knowledge base from your business info, docs, or website
  • Set up structured conversations that extract the details you need (bookings, leads, inquiries)
  • Implement RAG (Retrieval-Augmented Generation) so answers stay accurate and grounded in your data
  • Connect to your database or CRM when needed
  • Deliver clean, documented code you fully own


Background: I'm a backend & automation engineer with 2 years of production experience building AI-integrated systems including a document classification pipeline using the Gemini API for an enterprise client, and a fully offline RAG chatbot for disaster-relief scenarios.


I work in Node.js/Express with direct API integration no black-box no-code tools, so you get something you can actually maintain and extend.


Send me a message with what you need, and I'll help you figure out the right approach before we start.
