About me

I'm a Senior Product Designer with 6+ years of experience designing complex digital products — from enterprise logistics and healthcare to e-commerce and SaaS.

What drives me is watching real people use something I designed and seeing it actually work. That's why I lead with research and strategy — and why the products I work on are shaped around how people actually think and behave, not how we assume they do.

My work spans B2B and B2C platforms across the full design process — from discovery and user research through prototyping and delivery. I've worked on enterprise tools used by 1,000+ professionals across Europe, global Top-5 FMCG e-commerce platforms, and consumer mobile apps across healthcare and sports. I've improved registration conversion by 14.6% through A/B testing and reduced task completion time and user errors validated through usability testing.

I also lead multi-brand design systems — covering component architecture, design tokens, and WCAG accessibility — and have introduced documentation standards that improved handoff clarity and cross-functional adoption.
