Staff Product Designer with a front-end engineering background, focused on design systems, B2B SaaS, and complex workflows in travel, logistics, finance, and banking.

I build user-centered products and scalable design systems, lead cross-functional teams, and shape product strategy so design decisions stay grounded in real user needs and measurable business impact.

Currently helping organizations build AI-native, contract-driven design system workflows.

At FLYR I led Orville, the design system now behind every product in their platform. This work that helped ship a full booking experience in 6 months and supported a $295M funding round.

Based in Kraków, Poland, open to FTE and B2B roles.
