Full Stack JavaScript Developer | AI Integration

Building scalable, production-grade web apps — and the AI that makes them smarter.

🧠 About

Full Stack JavaScript Developer with 5+ years at ROITech Consulting (2019–Present), where I've grown from Developer → JavaScript Consultant → Specialist JavaScript Consultant. I build real products end to end with React, Next.js, Node.js, TypeScript, and PostgreSQL, and I integrate OpenAI / LLM APIs and automation into them — not demos, but features that ship and move metrics.

I care about performance, clean architecture, and code quality. Former educator — mentored 500+ students — which is still how I engineer: break the hard thing down, make it clear, ship the result.
