Learningthroughdesign
These are some core principles I follow when working on design projects. Each one shapes how I approach problems, collaborate with teams, and create meaningful solutions for users and businesses.
Iterative
Every product is a cycle of testing, learning, and continuous improvement. First drafts are rarely the best outcome.
Intentional
Good design makes hard things feel simple. Every decision should be informed, deliberate, and grounded in real insight.
Collaborative
The best solutions emerge from diverse perspectives. I value feedback, challenge assumptions, and build on collective wisdom.
Purposeful
Great design solves real problems. Understanding the 'why' behind every decision ensures meaningful outcomes for users.

Testimonials from colleagues, clients, and collaborators I've had the pleasure to work with.
"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."
"Mariusz is an incredible product designer. He always made my job as a Product Manager easy. His designs are always comprehensive. He immerses himself in the customer journey. His thorough research is evident in his designs."
"Working alongside Mariusz was one of the great privileges of my design career. He can take the most complicated problems and design beautiful and functional solutions with ease and swiftness. Mariusz is a true design leader and would be an invaluable teammate and asset to any design organization."
"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!"
"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."
"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."
