// 01 · Who I am

About Me

I'm a versatile software developer with 17+ years of experience spanning mobile (iOS, Android, Flutter), full-stack Java, and cloud infrastructure.

Over the years I've built betting platforms used by millions of users, contributed to an e-learning startup's 50% growth, and delivered enterprise apps for clients in Switzerland, the Netherlands, New York, and Australia.

I'm equally comfortable architecting a system from scratch and diving deep into legacy codebases to fix performance bottlenecks. I care about clean code, good UX, and shipping software that actually makes a difference.
