Skills

Cloud ComputingCloud PlatformCloud TechnologiesKubernetesGolang
For over a decade now, my work has revolved around developing for or running systems based on Kubernetes or the Kubernetes Resource Model (KRM).
For the last year, I've been working for different companies, but always within the NeoNephos Foundation on open source building blocks for cloud and edge stacks to advance the digital sovereignty of the European Union.

Currently, I work for Dell on the ecosystem around the Metal Operator, the bare metal management of NeoNephos' IronCore project. I develop the Metal Operator Test Framework used for Hardware-in-the-Loop (HIL) testing and the Metal Lab for testing against virtualised BMCs.

I have previously worked for companies such as SAP SE, IONOS Cloud and Cisco Systems Austria.

The projects I work on are usually a combination of infrastructure and software development. Examples include public or private cloud, platform-as-a-service or software-as-a-service solutions.

Additionally, because I have a background in hands-on systems engineering and networking, I understand how cloud-native technologies relate to the hardware they actually run on.

I am as proficient in automating infrastructure as I am in creating services, platforms or automation tools themselves.
