Product design

Designing Mycar.kz, an online car sales service

Mycar.kz is the major service for selling and buying cars online, which is based in Kazakhstan.

I’m a hands-on product design leader with 20+ years of experience creating digital products and 12+ years building and leading teams.

I’m now based in Utrecht, the Netherlands.

I was born in Minsk, a city of engineers where I learned early to enjoy figuring out how things work — and how they could work better.

Over the years, I’ve worked with startups, product companies, and clients across more than 100 projects. My work spans product strategy, research, UX, and UI, and I still enjoy being close to the craft.

I look at product challenges through a business lens and solve them as a designer. Research, Figma, AI, experimentation, and team building are all part of my toolkit — I choose what fits the problem rather than forcing a particular process.

Outside work, you’ll usually find me kayaking, gaming on my Steam Deck, or exploring a new place on foot.
