About

Shipping production code from Athens, Greece.

I go from concept to deployed product fast. My core stack is Next.js, React Native, and Express on the web and mobile side, with ESP32 and PlatformIO for IoT firmware. I build things that work at scale, fix them when they break, and harden them until they stop breaking.

Available for freelance projects and long-term contracts. Multilingual across four languages.
