About this gig

Want AI features in your app that actually work in production - 

not just a demo?


I'm a Full-Stack Developer specializing in AI API integration. 

I connect OpenAI, Claude, and Gemini to real applications - building 

chatbots, automations, and AI-powered features that handle real 

traffic, real data, and real edge cases.


WHAT I BUILD:


Custom AI chatbots with conversation memory

RAG systems - AI that answers based on YOUR data, not generic info

AI-powered automations and workflows

Backend integration for OpenAI / Claude / Gemini APIs

Production-ready code with proper error handling


TECH STACK:


TypeScript JavaScript Python (FastAPI) PHP Node.js 

PostgreSQL MongoDB REST APIs


WHY WORK WITH ME:


I write real, scalable backend code - not no-code workarounds

I understand architecture, not just "API calls"

Clear communication, no technical jargon dump

Support included after delivery on every package


HOW IT WORKS:


1. Send me your project details (even rough ideas work)

2. I respond with a clear technical plan and accurate quote

3. You get working, tested, documented code - ready to deploy


Got an existing app that needs AI features? Starting from scratch?
