About
Where the code comes from: a Swiss apprenticeship, service with the Stützpunktfeuerwehr Laufental, and a stubborn habit of taking things apart to see how they work.
Full-Stack Developer
How I got here
I am a Java-focused full-stack developer from Laufen in Basel-Landschaft. I finished the four-year Swiss IT apprenticeship in 2025 and now write microservices and REST and SOAP wrappers. Mostly Java with Spring Boot, increasingly Go, running on Google Cloud.
Before software I trained as a retail specialist for consumer electronics. That background still helps: explaining something technical to someone who did not ask for the technical version is half of the job.
