Angular, design systems, and a habit of shipping side projects at midnight.

“Clean architecture,

Based in Poland
Open to remote

I'm a frontend engineer and designer with 15+ years building digital products across Poland, Australia, and the UK.

I started as a designer, learned to code because I got tired of things not looking right in the browser, and never really stopped doing both. At InPost I'm building micro-frontend platforms at European scale. Outside of work I'm a solo founder — shipping apps like CYA, Brain Spill, and Voxa, usually late at night, usually with too much coffee.

I care about clean architecture, interfaces that feel obvious, and code that a future me won't hate.

What I Do

Three ways I can help.

01

Frontend Engineering

Angular micro-frontends, NgRx, Signals, RxJS, component libraries, Nx monorepos. I write production code and make architecture decisions — not just tickets.

02

UX / UI Design

From user research and wireframes to pixel-precise prototypes. I've designed for firefighters, energy traders, and credit analysts. Context always comes first.

03

Product & Founding

I build SaaS products independently — full stack, from idea to App Store. CYA, Brain Spill, Voxa, and Proofmark Camera are all live or in active development.

General

Design systems that actually get adopted

I’ve worked on design systems from both sides — as the designer building the Figma library, and as the engineer trying to implement it. I’ve seen more of them fail than succeed. The failure modes are almost always the same.

The Role of Feedback in UX Design

In User Experience (UX) design, feedback is essential to creating effective, user-centred products and services. It helps designers understand user needs, identify potential issues, validate decisions, and continuously improve the experience over time.
