A selection of projects I have designed, built, or co-founded — from custom poster shops to digital presences for the construction industry.

The shared account for groups without a legal form.
Banks usually only open an account in a group's name for registered associations. Noah is the joint account for everyone else — school classes, sports teams and clubs: the money belongs to the group, not to one member who is personally liable. I co-founded Noah in 2026 together with Fabian and Luis and build the product as CTO — from architecture to the last pixel, on the same Deno Fresh stack as this site.

Turn your favorite songs into personalized posters.
artwerk is a passion project I co-founded with two friends. Our mission is to transform your favorite songs into personalized posters, capturing the essence of music and memory in unique visual art. In just seconds, you can create your custom poster and see a live preview. We prioritize high-quality printing on premium paper, produced in an environmentally friendly manner. artwerk is the perfect blend of personal taste and design — a tribute to the tunes that move you.

Smaller things I build for myself — open experiments living on GitHub.
Flutter · OpenStreetMap · MIT
Local-first GPS tracking & route planning for Android.
A free, open-source alternative to Strava and Komoot. Records your rides with background GPS tracking, plans routes with multiple profiles via BRouter, imports and exports GPX, works with fully offline maps and even generates personalized training plans — all local-first: your data stays on your device, no accounts, no cloud.
View on GitHub ↗Kotlin · Jetpack Compose
A minimalist pixel-style reaction game for Android.
One dot, your reflexes, two game modes: FLIP lets you invert gravity to dodge obstacles, STOPP is all about freezing time at exactly the right moment. Local highscores per mode, pixel aesthetics, haptic feedback — built natively with Kotlin and Jetpack Compose.
