About

A short
history lesson

My passion for computers started exactly where you might expect: Playing Old School RuneScape in primary school. By high school, I wanted to know how things worked under the hood, which led me to build a very basic Tor simulation in Java for my graduation project.

After my mandatory military service, an internship supporting ERP systems at a large food manufacturer gave me my first taste of enterprise IT. It also taught me an important lesson: I didn't just want to support software, I wanted to build it. This drive pushed me to pursue my Computer Science degree at ETH Zurich to build a deep, rigorous foundation in the field.

Today, I'm a Technical Lead and Software Engineer for the Swiss HIV Cohort Study. This includes steering the development of various Django and Java applications as well as a in development React Native mobile app for participants.
