Manifesto / 03 principles

Software should feel calm when everything around it is moving.

I care about systems, speed, clarity, and the small details that keep products alive.

  1. 01Build systems that hold up
  2. 02Move fast without losing craft
  3. 03Keep interfaces clear and honest

Selected builds

Real systems, compact teams, practical pressure.

Origin / South Tyrol to St. Gallen

I grew up around mountains.

That shaped how I think: stay calm, read the terrain, move with intention.
