DESIGN IS

"Mariusz is a phenomenal designer and the reason we were able to build so rapidly. His turnaround time on high fidelity mock-ups was incredible and we rarely had to iterate on his initial designs because he understood the product and our users so well."

Claire Tsukuda

"Mariusz is an absolute pleasure to work with. He's a seasoned design leader and does an excellent job managing the customer and business goals in tandem with the product design. I give him my highest recommendation!"

Jordan Lunetta

CEO @ Kiro

"Mariusz is an excellent product designer, whose superpower is a deep insight into his customers. His curiosity in understanding customer pain points is clear in his user-centric solutions, and he looks beyond current product limitations to design the right product for customers."

Sarah Sandberg

Lead PM @ LILT

"Mariusz has a great combination of skills. He's highly creative, very technical, and very practical at the same time. I worked with him on a highly innovative, boutique product that needed to bend the rules from anything we have done in the past. Mariusz was the perfect designer for this. He was always steps ahead of me and brought really great ideas to the table that made large impacts to the product and still worked within our timeline."
