Building digital experiences
of tomorrow

I'm a Senior Software Engineer based in London with 10+ years of experience building mobile and web applications. I specialise in React Native, TypeScript, and modern JavaScript frameworks.

My journey started with curiosity about how apps work — now I build them daily. I care deeply about clean architecture, smooth animations, and experiences that feel effortless to use.

When I'm not coding, you'll find me at the gym, exploring London's food scene, or researching crypto markets and property investments.
