Piotr Brzeziński — UX/UI & Product Designer in Poznań

I'm Piotr — Product Designer / Design Engineer based in Poland, deep into Design Systems. I build slick SaaS products, apps, and websites - down to the details that make them click.

Currently, I'm focused on growing in AI and design engineering. I build projects in code from the very start, checking my work with developers along the way. This new way of designing, where a designer can work in code, really excites me.

I'm also a fan of sharing knowledge - whether it's mentoring teams, giving feedback, helping people level up in Figma, or showing how AI can actually make our work smarter, faster, and more fun.

How I work

Listen
A short call and a written brief: who it is for, what done looks like, what must not break.
Prototype
Ideas go into a clickable prototype early, often in code, so we judge the real thing, not a picture of it.
Build together
I work with your developers from day one: reviews, handover and the details checked in the browser.
Hand over
Documentation, components and a team that can carry it on without me.
