I'm a Cyber Security Architect based in Koblenz, Germany, specializing in identity security and cloud-native solutions on the Microsoft platform. I've been awarded Microsoft MVP in Security since 2020.
Here's what I'm building and contributing to:

My focus is on the Microsoft security stack - from identity and access management to threat detection and cloud security posture.
