About Me
Hi, I'm Kate — a Product Designer from Kyiv, Ukraine.
I work with startups and product teams worldwide to turn complex ideas into products people actually enjoy using. Whether it's a SaaS platform, a data-heavy dashboard, or a product from zero to one, I focus on clarity, usability, and making the experience feel effortless.
I'm involved from day one — discovery, information architecture, design systems, and everything in between — until the product ships.

Kateryna was AMAZING! She worked fast, she created a great product, she stayed in close communication during the project, she went out of her way to help with additional tasks, she's a problem solver, and she created a fantastic and artistic series of 30 products for me. I will definitely be working with Kateryna again. Top-notch service!

Very quick and efficient. Kate created beautiful designs in a way that was very easy to build. Her original ideas were great and she responded very well to feedback and implemented it well. I would recommend Kateryna to anyone looking for high quality app design.

Kateryna helped us create a suite of illustrations for our brand redesign. Her original ideas were great and she responded very well to feedback and implemented it well. I would recommend Kateryna to anyone looking for high quality illustrations at a competitive price.

Kate is absolutely fantastic to work with and is one of the most hardest working colleagues I have ever worked with. Kate handles stress like it's a piece of cake and her designs are so on point with what we were looking for and Kate brought so much to the table in her designs that we could never have imagined ourselves. We are so lucky to have worked with Kate as she really pointed us back in the right direction. Kate was very patient with hurdles that come up and really dug deep for us in pinches for turn around. Kate created a great atmosphere in the team which allowed everyone to perform their best. From the quality of Kate's work to the experience of working with her, I can only say you're lucky to work with Kate if she's free!!
