Mateusz is one of those designers who can take over "I have this idea and here's what we know about it so far... Play with it and see if there's something?" and put it together for you and also a kind of top of the class UI designer who would execute the final pixels of everything with the last detail considered and systemise it.

About

Hi, I’m Mateusz 👋

I’m a product designer and no code developer helping founders shape and ship digital products.
I focus on product design and design systems, from early concepts to production-ready interfaces.
I’ve worked with SaaS companies like TwentyThree and Instream CRM, leading design on new features, redesigns, and full system overhauls.
