Headline: Senior Developer bei Jung von Matt TECH
Location: Hamburg, Hamburg, Germany

## About

I've been in frontend development for nearly 9 years — starting with an apprenticeship at Jung von Matt TECH, a digital agency in Hamburg, where I've grown into a Senior Developer role focused on TypeScript, React, Next.js, and Hugo.

What drives me beyond shipping features is the craft underneath: **accessibility (a11y)** as a baseline for quality, **sustainable web development** as an ethical responsibility, and the open, decentralized web as what the internet was always meant to be.

I write about CSS, green web dev, and frontend craft at **lemm.dev** — published POSSE-style, because I believe in owning your content.

When I'm not in the terminal: being a Dad, (analog) photography, bouldering, D\&D, learning piano/guitar.
