Hi, I’m Marcin.

I’m a software engineer from Łódź, Poland.

These days I focus on general software development with AI, and I especially like working on AI development environments. You can see some of it on the My Work page. Since 2021 I’ve been working at Cheddar, a UK app that gives people instant cashback at retailers like Tesco and Nike.

Fidev is the company I use for freelance work, together with my wife Monika, who is also a software engineer.

Before AI, my main area of expertise was Flutter. I started building with it in its alpha days and began this blog because I believe sharing is caring, and the framework was young enough that a lot of things still needed explaining.

I loved watching beautiful designs become real apps, which is why so many posts here rebuild a design in Flutter, one animation at a time. Along the way I gave a talk at Flutter Europe and released a few open-source projects. You can also see the apps shipped under the Fidev name in past work.

Away from the keyboard, I’m happiest on a sunny beach far from home.

A few things I built with Flutter

What I care about

  • Make it beautiful. Always.

    Apps should stand out among everything else on someone’s phone. Usually the biggest constraint is creativity, not the tools.

  • Extreme ownership

    Take responsibility for everything that affects the work, and care about the details with the end user in mind.

  • Straight talk

    Say things as they are. The hard truth beats drifting along in sweet lies.

Say hello

Got an idea, a question about a post, or a beautiful design that needs building? Email is the best way to reach me.
