Winterthur · educator, coach, developer

Classroom, football pitch, crêpe stand and code.

I support kids in the classroom and on the pitch, run a crêpe stand on weekends, and in between I build the apps I was missing along the way. All self-hosted, no tracking.

What I do

Four things that feed each other

Gastronomy

Crêpes at the de Luc's Büx wagon – at markets and festivals around Winterthur – plus the till I built for it.

School

Teacher's assistant in Winterthur: supporting lessons, collecting games and songs.

Football

Youth coach at FC Töss and SC Hegi – with apps for fixtures, tables and tournaments.

Projects

SvelteKit apps and a self-hosted homelab – all documented in the open.

FindMore - A Public Football PWA on a Shared Cache

How FindMore is built: a SvelteKit 3 static PWA without a backend of its own, one stale-while-revalidate cache that pages only read from, a hand-written service worker, a federation client shared with KnowMore as an npm package, and link previews for messengers without SSR.

Building Kasse - A Point of Sale for a Crêpe Stand

How Kasse is built: a SvelteKit PWA and PocketBase with Go hooks in one container, money as integers in Rappen, every invariant enforced on the server, receipts booked as one transaction, and a kitchen screen that cannot double-take an order.
