About Me

Full-stack developer who ships across web, desktop, mobile, and CLI

What I Build

Based in Belgrade, Serbia, I bring over a decade of experience spanning full-stack web development, enterprise automation, and AI-powered solutions. From Laravel backends to React frontends, from desktop tools to cross-platform mobile apps. I build across the entire stack.

My journey started with freelance web development while still in school, grew through 7+ years at NCR (Fortune 500), and continues today leading the DCS Automations team while freelancing alongside co-developer Dušan Ivančić.

I've shipped security audit tools, ERP systems, cross-platform analytics apps, content platforms, and a private jet booking site, each built end-to-end, from database to UI.

"I'd rather ship one clean tool that solves a real problem than a bloated platform that solves none."
