I write code for a living, mostly apps. Since 2025 I work in-house at Vaillant on myVaillant Pro, from Katowice. Off the clock I travel (Asia, a lot), train Muay Thai and never say no to a tea. Three side projects are in the air.
Draw them a tiny love note. An iPhone app for two people: a sheet of paper, your finger, and a widget on their home screen. No chat, no feed.
liebesbriefe.app →Translate it. Ship it. Hear about it. A translation workspace with machine-translation review, GitHub sync that never writes without approval, and a public feedback board.
localblok.com →Turn your city into a game. An iPhone app that makes running a territory game: claim zones by running loops, defend them with your team, climb the leaderboard.
