Voice of my Coworkers
Peter Kaleta
Head of Product / Software Developer @ Masterplan.com
I am delighted to recommend Katy as a top-notch UX & product specialist. I had the privilege of working with her on strategic, tactical and operational levels in Masterplan as the Mobile Engineering Lead and later the Head of Product. As product specialist, her skills and expertise never failed to impress me. Katy is an incredibly talented and dedicated professional who consistently delivers outstanding results both as an individual contributor and team member.
Corinne Ruckstuhl
Product Manager @ Locatee
I had the privilege to work together with Katy in the same Product and Scrum Team. Not only does Katy possess a very sharp mind, always asking the right questions and displaying a deep understanding of user research and user-centric design, but she's also very easy and fun to work with. I was constantly amazed by her fast thinking and her ability to connect the different dots between the product, the user needs and the technical aspects. I've always really really enjoyed working with her and it would be an honour if our path crossed again!
Hitesh Sawlani
Product Manager @ Locatee
I had the pleasure of working with Katy at Locatee where Katy was instrumental in building up the design team, establishing a much-needed design system for our core product. Katy was an active and engaged member of the product trio; designing and running experiments with our users to test our product hypothesis. I'd highly recommend Katy for any product-led, customer centric organisations!
Aga Kaim
UX Researcher @ Masterplan
I had the pleasure to work in a remote UX team led by Katy. She is one of the most impressive professionals I’ve ever worked with. Her UX expertise and her dedication to team members are remarkable. What impressed me the most was her ability to take care of the design details without losing sight of the larger business context. Under her guidance, I gained a variety of useful skills. Any organization would be lucky to work with Katy.
My design manifesto
Design isn't decoration—it's human psychology in action.
Great design understands minds, not just trends. While others chase aesthetics, I dig into why people click, scroll, and convert. Every pixel serves a purpose rooted in how we actually think and behave.
AI doesn't replace creativity—it unleashes it. I prototype at lightning speed, explore impossible ideas, and push boundaries that manual methods can't reach.
"That's how we've always done it" is the enemy of breakthrough. I question sacred cows, challenge conventions, and find better paths forward.
Beautiful design that doesn't drive business results is just expensive art. I create solutions that look stunning & deliver measurable impact.
The future belongs to designers who experiment fearlessly, fail fast, and iterate faster.
Katy Bak.
