Designing 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 based in Utrecht, with 20+ years in digital products and 12+ years building and leading teams.

Born in Minsk, I studied management first, then design. That combination still shapes how I solve product and business problems.

Most of my career has been in agencies, with 150 projects in the last seven years alone. I’ve built design teams from scratch, grown them to 20+ people, and co-founded two startups, taking products from concept to market.
