Good design is invisible. It just works. I build products that are accessible, fast, and actually useful — not just pretty.

I come from product design but spend most of my time writing code these days. Front-end development, design systems, TypeScript — that's my zone.

Outside of work, I'm usually gaming, watching movies, or exploring Amsterdam for good food.

When I'm not building things, I'm usually running around parks hitting segments like they're Super Mario levels — chasing PBs like Power Moons..

So far this year, I ran:
