About Me

I’m a DevOps Engineer based in Vienna, Austria. I am 34 years old, and I live with my loving wife and our 9-year-old son. Professionally, my area of work has shifted from being a pure software developer to building up all our tools needed for automation and GitOps. I am also involved in occasional product development direction planning, software architecture, and onboarding and scheduling new employees. I maintain a deep focus on stable operations for large-scale enterprise systems and specialize in Single Sign-On (SSO) implementations, working within Agile environments and often leveraging AI-assisted development tools to streamline troubleshooting and coding.

My fascination with computers started early: from summer programming courses in Volksschule (elementary school) and reading Visual Basic books as a kid, to learning touch-typing on an electric typewriter during Gymnasium (grammar school).

My Linux journey began with years of distro-hopping, eventually leading to Fedora, which aligns with my professional focus on RHEL. I actively use and contribute to KDE development, constantly finding and improving the desktop experience based on what I personally use and need.

Beyond my professional life, I am a passionate Homelab enthusiast managing about 50 containers, and developer of porturl—a comprehensive SSO portal featuring a Spring Boot backend, a React Admin web frontend, and an Android application.
