Description

I'm Nikolas — a frontend developer based in Rotterdam with a background that most people don't expect. Before writing a single line of production code, I spent 14 years as a practising architect in Athens, managing projects from concept through to construction.

That background didn't disappear when I switched careers — it sharpened how I approach frontend work. The same thinking that goes into a building's spatial hierarchy, material consistency, and structural integrity maps directly onto component architecture, design systems, and performant, maintainable code.

I've been living in Rotterdam for around 7 years now, and I work primarily building interfaces that are as considered under the hood as they look on screen.
