About.

I'm Jaroslav Maša — a developer, musician, and designer working from Prague and the internet. I build web applications for people who care about the details, and I make music and graphics when the code goes quiet.

My work sits at the intersection of engineering and craft. Whether I'm shipping a full-stack product, mastering a track, or typesetting an editorial layout, the intent is the same: leave something considered behind.

This site is a living index of that output. It's updated by hand — often on Sunday evenings, usually with a coffee going cold on the desk.
