Software Architect

Zurich area, Switzerland

Great solutions come from understanding problems end-to-end, from design to implementation. I find energy in that challenge: distilling complexity into simplicity. For me, software engineering is as much about the how as the what.

I design and build software systems that are reliable in daily use and remain maintainable over time. My focus is on Java, Spring Boot, and microservice architectures. Over the past eight years, I have been working on solutions where clarity, stability, and clean structure matter more than quick shortcuts.

Security and identity topics are a natural part of my work, especially around Keycloak and OIDC. I also reach for event-driven or reactive approaches when they actually make things better. DevOps and automation pull me in too. I like making delivery pipelines and cloud-native setups work well, not just exist.
