what i do

at gateway ventures

I'm responsible for calmar.vc: what we build, how we price it, and how we bring it to market. I work with our team and development partner to put those decisions into practice.

building with ai

I use Claude Code, Cursor, and Codex to build prototypes and internal tools. A working version gives me something concrete to discuss with the team and improve together.

my own projects

Alongside my day job, I built Fin Cinema, an iOS app for Vienna's arthouse cinemas. I look after the app, the showtime data, and the infrastructure myself.
