Warsaw — Product design & indie iOS
Designer at Mastercard, former co-founder of Swayze. I work across product, brand and strategy — and build things of my own along the way.
A marketplace pairing nano-influencers with brands. We reached 40K+ users and 300+ brand partners, hit Top 3 in the Polish App Store, and raised a pre-seed round. Then we closed it. I learned more here than anywhere else.

On the creative desk: design systems, campaigns, and AI enablement across three regions. I also help lead AI adoption inside an internal task force — getting designers to actually use the tools, not just talk about them.

A flashcard app for learning Mandarin. HSK 1–6, spaced repetition, pinyin audio, a lock-screen widget. I built it because I was learning myself and nothing on the shelf felt right.

Cycle tracking without the clinical dashboard. A flower that opens and closes with your phases, gradients that shift as they move. Calm, not clinical — the way this kind of tool should have felt all along.

Led an 8-person team developing a technology-for-good concept as part of Huawei's Seeds for the Future programme. Our project was selected among the Top 6 teams in Europe, taking us to Athens for the programme's final showcase.

Everywhere I go, I collect design — the small decisions most people walk straight past. A few notes from the field.
One foot in a startup mindset, the other in a global company — and I've stopped thinking I have to choose.
I'm a product designer in Warsaw. I co-founded Swayze, scaled it, and closed it. These days I design across CEE, DACH and BeNeLux on Mastercard's creative desk, and build my own iOS apps on the side.
I'm learning Mandarin, which is where Chá came from. I care about friction, dark patterns, and the decisions most people never notice. Usually the small decisions turn out to be the whole thing.
