Front-End Developer • Visual Artist Poland

I combine a painter’s eye with engineering discipline to build interfaces that are both expressive and scalable.

Story

Art background → web technologies → enterprise systems → product work.

I'm a Front-End Developer specialising in UI engineering and design systems for enterprise-scale products.

Over the past decade I've built and maintained large web platforms for global organisations, working with AEM-based component libraries, responsive layouts and multi-market sites.

I collaborate closely with designers and UX teams, translating Figma concepts into robust, accessible, production-ready interfaces with clean, maintainable code. Alongside this, I develop Zafiro – my own three.js-powered 3D web application for immersive, relaxing world-building – where I combine solid front-end engineering with a fine arts background.

How I work

What you can expect when we collaborate.

Holistic design

Aesthetics, usability, and implementation constraints are treated as one system.

Component thinking

Reusable UI primitives, strong semantics, and predictable interaction patterns.

Performance-aware

I anticipate constraints early: bundle size, rendering cost, runtime budgets.

Practical craft

Beautiful outcomes that ship reliably and scale with teams and time.

Toolbox

Technologies and practices I use most often.

Selected work

Product work, systems, and art-driven UI.

Zafiro — browser-based 3D world editor

A WebGL/Three.js-based project where I merge UI engineering with real-time rendering constraints. Focus: usability, visuals, performance.
