About

I build systems that stay correct after I hand them over.

Betriebsinformatiker EFZ, trained at F. Hoffmann-La Roche across Manufacturing IT, Roche Services & Solutions, and PRED Data & Analytics.

Currently completing an IT internship at Baumann & Cie, Banquiers in Basel, working on report consolidation and test automation.

What I hand over is documented, tested, and boring in the best way.

I enjoy learning new things and building solutions that continue to work tomorrow.
