Career

The 1990s – The decade as a system operator

After my time in the military and my side job as a programmer, I started my professional career in the early 90s. For the first few years, I worked for an insurance company, where I dealt with IBM systems. Later, I was an administrator of high-availability Solaris clusters and a few Linux servers. These were really nice systems that shaped my affinity for Linux.

On the side, I continued to develop software and learn new programming languages. That’s how I established myself as a technical writer, first about Java.

The 2000s – Diverse software developments

In 1999, I made the leap into the professional world of software development. As a team leader, as vice president of software development, as managing director of software development and as a project manager with ambitious teams and beautiful projects in Java. As a team leader, I got to know message busses and event processing and worked with Smalltalk, which was really great.

My interest in concurrency led me to Erlang/OTP and Go. The latter then also spawned my only book so far.

The 2010s – Off to the clouds

It was precisely this call that led Canonical to ask me if I would like to work in the world of remote work and cloud systems. It was a really great time with a great team worldwide and regular meetings everywhere. After that, I only worked on-site for a short time, here as a project manager for logistics software. But otherwise it was always remote and always in Go. The work as a team lead at Kubermatic was also really good. There we developed a product and also managed special projects around Kubernetes.

Since 2020 – An architect without buildings

I’ve always developed software architectures, sure. But in 2021, I was able to get off to a flying start professionally as Director Enterprise Architecture. And today? Today, I work as a Principal Enterprise Architect in the world of clouds again with the Open Telekom Cloud.

Funnily enough, when I graduated from high school, I still planned to study architecture. But I achieved it indirectly.
