A little about me

Product designer, eleven years in, across consumer products, SaaS and enterprise platforms. I work where product direction meets the details that decide whether it holds up — the state nobody drew, the step that happens off the screen, the number that doesn’t add up.

Born in Kyiv, based in Barcelona. I’ve been the founding designer on a 0 → 1 trading product, the lead on a consumer rebrand and the first end-to-end journey built on top of it, and a senior designer inside a large travel platform. I also lead and mentor — most recently a team of five, taking them from junior to middle.

Teaching & speaking

200+ designers taught across eight cohorts, two of them international with ABB. Curriculum, weekly workshops, and mentoring designers from junior to middle.

Workshops & talks
  1. 01 / Find the right problem

    I check whether the problem is the one people named. A Momenticket audit started from a conversion funnel and ended by disproving it — the instrumentation was broken and the real number was twenty times higher. At Jome nothing in the analytics asked for a rebuild; the buying journey already existed, hidden in a header dropdown that closed when you clicked away.

  2. 02 / Make the idea tangible

    I design the version that can be tested, then let the test win. The Jome hub was first drawn as five stages revealed one at a time — the kinder-looking option, and the wrong one. Unmoderated testing showed that hiding the next steps disoriented people rather than calming them, so it shipped as nine steps on a single screen.

  3. 03 / Build it together

    I design inside the constraints the team actually has. At Kiwi that meant an SEO component library that cut experiment cost threefold and let the team ship pages without me. At Vantage Lumber it meant turning a founder’s trading knowledge into rules an engineer could build and a trader could argue with.
