About

Founder and developer with 9+ years building scalable platforms and consumer web applications. I specialize in frontend architecture, interactive experiences, and full-stack delivery — from pixel-perfect UI to production-grade APIs.

Currently open to freelance or short-term contract work — especially creative, data-heavy, or consumer-facing web apps. I enjoy working on things that are technically interesting and make a real impact.
