Dominik Księżyk

Senior Product Designer who ships products.

I specialise in financial products like neobanks, mobile banking, leasing platforms used by millions of people. Currently leading design at ICEO Venture Builder. Previously at Ailleron, working on products for BNP Paribas, Santander and VeloBank.

Using AI tools like Claude Code and Figma AI, I've built workflows that reduce back-and-forth between design and development. I introduced these tools to the whole team, cutting time spent on research, documentation, and handoff.
