Product Designer · Kraków

Hi, I’m Arina. I design products that turn browsing into buying, backed by research and measured after launch.

6+ years across retail, healthcare and e-commerce. I find problems in real user behavior, test the fix, and measure what it changed.

How I use AI

AI speeds up the work around research and design. Decisions still come from real users, real data and testing.

  • Discovery and research

    Synthesizing interviews, affinity mapping, drafting hypotheses and interview guides; synthetic users only for early idea checks.
