About me

I'm Olena, a product designer based in Wrocław
and working remote, 4 years in design.
Before that I spent 10 years in international trade
and procurement, so I read a product the way
a buyer does: what it promises, what it costs
and where it stalls.

  • Interviewing people before drawing a single screen
  • Building what I design, in SwiftUI
  • Trying new AI tools on real work, not demos
