Having worked as a DevOps engineer, software engineer, system administrator for 9+ years, I love providing scalable, reliable and secure infrastructure as well as automating software development processes. I feel at home on Linux, in the Kubernetes universe and the cloud.

Broad knowledge of network protocols, internet services and databases allow me to set up, operate and monitor complex service architectures and environments. I enable developer teams to test and deploy their software by establishing automated CI/CD toolchains. In my work I combine modern tools and time-proven technologies with a focus on open-source and industry standards.
