About Mariusz
Product designer and design leader with almost two decades of experience.
I believe great experiences come from understanding problems deeply and validating ideas quickly through prototypes.
Over the course of my career, I've worked with companies big and small, helping them build scalable design systems, design teams, and digital products. I strongly believe in hypothesis-driven, iterative design.
