I'm Yannic. I design and build software people live in — Koukai, a private photo-sharing app; Anvil, a shared pixel-art MMO; and Kioku, a quiet time tracker. In between, I paint.

Anvil
A cozy pixel-art MMO on a shared island — gather, craft, farm, raise animals and build a home in a world that keeps going when you log off.
Kioku
A privacy-first desktop app that automatically tracks which applications you use and for how long — no manual timers, all data stored locally.
Kizuna
A self-hosted Discord alternative with real-time text chat, voice channels, and screen sharing — you host the server, you own the data.
