Introduction

Jakub Pelczar

Hi, I’m Jakub.

I’m a Staff Software Engineer with 10+ years building web products end-to-end — from design systems to shipped, monitored UI. I move fluently between React and Angular, and I care about the parts most engineers treat as somebody else’s job: the token that’s one shade off, the state that’s one frame too slow, the detail nobody asked for but everybody notices.

Skills & Stack

What I work with.

language JavaScript, TypeScript
frameworks React, Angular
focus Design Systems
lifecycle design → build → ship → monitor

What I Do

frontend-architecture Scaling component systems and app architecture for teams, not just features.
design-systems Building the shared language between design and code — tokens, components, contracts.
product-engineering Full lifecycle ownership, from design through what happens after it ships.
interaction-craft Sweating the interaction and motion detail most teams skip — this page is the demo.
