Open to Senior, Lead and Design Director roles · Remote

Senior product designer for B2B SaaS and AI.

10+ years, 40+ products, many of them built 0→1 with founders in the US, EU and MENA. I start where there’s no design yet: the system first, then the product, the brand and the site. Founders say I get context fast.

What I do

Behind
the work

10+ years designing B2B software. EdTech, cybersecurity, PropTech, fintech, AI. I started with C++ because I wanted to make games. It wasn’t for me. Then film editing and motion, CD covers for hundreds of releases, game interfaces, and then UX, where I stayed: Rehegoo, six years at Selleo, direct with founders, and now Bezto, the studio I run with my co-founder Sylwia.

Small town in Poland, a factory job, design after hours. On my first day at the factory I drove home and started planning how to get out. Now I’m in Bielsko-Biała, I train MMA, I’m building a house in the Beskidy foothills, and there’s usually a side quest going: hotkeys.design, a documentary about Henryk Łapiński.

Most of my work is zero-to-one B2B SaaS and AI, where nobody has a playbook yet. Audit, UX, the design system, the brand, and code when it makes sense. Next I want to do that inside one product team, as a Senior, Lead or Design Director.
