I design at the intersection of product thinking and visual craft. My work is about turning ambiguity into clear decisions — and clear decisions into interfaces people actually want to use.

From people I've had the pleasure of working with.

Anna WróbelHead of Product, Mono Labs

“Working with Kamil felt like having a co-founder who happened to also be a world-class designer. Delivered the design system in half the time we budgeted.”

Tomasz KaczmarekCTO, Atlas Studio

“Sharp instincts, clear communication, and zero ego. Exactly what you want in a lead designer.”

Marta NowakCEO, Studio Lattice
