Julian Sallaberger
I build software that feels considered, from the data model to the last 20 milliseconds of an animation.
Selected Work
A few projects that show the range of my skills. Each one has a case page explaining what the problem actually was and what i built to solve it.

Built a game the company still takes to every trade fair
Schwarzmüller

About
I am a full-stack developer based in Austria, most at home in TypeScript and most interested in the seam between the data and the interface — the part where a good schema quietly makes the frontend easy, or a bad one makes it impossible.
I work best when I can see the thing running. I build the ugly end-to-end version first, put it in front of someone, and let what breaks decide what to build properly. Most of what I know about error states I learned from watching people hit them.
Away from the keyboard I cook a lot, which is where the recipe app came from, and I keep an e-ink board by my door telling me when the next tram leaves, which is where I learned that the interesting part of any integration is what happens when the other side goes down.
