02 / THE PERSON BEHIND THE CODE
More than
just code.
Matze / aka matooo
I’m curious about how things work. And how to make them a little better.
I study computer science in Tübingen. My projects bring together software development, artificial intelligence and practical ideas — from workout tools to personal everyday companions.
Away from the screen, calisthenics, fitness and nutrition are part of my everyday life. My background as a paramedic adds another perspective: technology matters when it helps people.
