About me
People before pixels
where the psychology comes from
Before I draw a screen I want to understand who will see it and in what situation. What interests me most is how people react to an interface and why - enough that I am finishing a degree in psychology. Next to Figma, it is my working tool.
Startup adrenaline
the environment I work best in
I work best where a lot is happening: a small team, fast decisions, a product that changes every week. That kind of work forces you to be creative - and that is what I love most about this profession.
From Figma to production
the whole chain in one pair of hands
I design in Figma and build what I design myself - in Angular, with accessibility in from the first sketch. I like seeing the whole road: from the idea, through the design system, to tests and release.
Think first, build second
it is wise to think sometimes
First I try to understand the problem properly, then I “break” it a little in my head - walking through scenarios, edge cases and the places where something could come apart. That way, fewer things have to be discovered only after release.
Beyond code
Inclusive design
I design for everyone - with accessible, inclusive language and interfaces.
Psychology
I study how people behave to build products that truly help - I am finishing a degree in psychology.
Woodworking
I build wooden furniture with my own hands - it teaches balance and clarity.
A wooden house at the end of the world
I live in a village in Podlasie - far from the city, close to the forest.
Let’s build something meaningful.
I’m open to new opportunities and collaborations. Whether you have a project, a question, or just want to say hi - I’d love to hear from you.
