From pixel to platform — I craft thoughtful web experiences that translate complex concepts into intuitive tools and applications.

About me
Developing digital experiences, not just code
Hi, I'm Lars — a full-stack web developer based near Heilbronn, Germany. I started my journey in web development back in 2017 and quickly developed a deep passion for crafting complete, functional applications that optimize processes and genuinely the end user.
Currently, I work at Schwarz Digits(opens in a new tab), where I am a proud core team member of onyx(opens in a new tab) — an Open Source design system built natively for the Vue.js ecosystem. Prior to this, I honed my skills over several years working in an advertising agency and taking on various challenges as a freelancer.
When I'm off the clock, I am a dedicated technic enthusiast. I love spending my spare time diving into new tech trends or programming fun and useful personal projects to keep growing as an engineer.
