Want to know my whole story?
I started programming as a teenager when I got my first home computer, a Commodore VIC-20, in 1984. During the following years, my computer skills grew with my continuous system upgrades. Studying computer science was an easy decision. Even before I started university, I worked as a freelance software developer. In my final uni years, my entrepreneurial streak grew stronger. Together with a friend and fellow student, I started a system and network administration company. This taught me a lot about running a business, but it also almost cost me my graduation.
After finishing with a bachelor’s degree in computer science, I got a job as a web developer. It was the end of the 90s, time to learn about all things Web. After my limited contract ended, I wanted to do my own thing again, so I founded a Linux consulting business, again with a friend. Over time, it morphed into an open source training business. I spent many weeks at SuSE Linux training centres and company headquarters where I taught people about system administration and software development.
This led me to WEB.DE, one of the biggest internet services in Germany. They commissioned me to design and teach a multi-month training programme on advanced system administration. When it finished, WEB.DE offered me to start, lead and grow a new team whose focus would be running some of the company’s most critical IT services. I accepted, and in the following years, I learned a tremendous amount about IT management and operating large-scale IT systems as a team. After WEB.DE was acquired by internet giant 1&1 (today trading as Ionos), I got promoted to lead a department of multiple teams handling essential backend services for their growing web, email and advertising service architecture. However, the entrepreneur in me was stirring again.
In 2009, I left 1&1 to launch freistil IT, a team of experts in high-performance web hosting. This opened up another steady stream of learning experiences, from designing, building and operating a highly scalable web hosting platform to hiring, leading and losing great team members. More than a decade later, I still enjoy running this company.
Over the years, I have…
- …founded multiple businesses.
- …led many complex technical projects.
- …optimised the processes of teams, departments and organisations.
- …designed and conducted numerous Dev and Ops training curriculums.
- …given an online conference talk on remote team communication to 13,000 Twitch viewers.
- …designed, built and operated a web hosting platform serving tens of millions of web requests every day.
- …taught hundreds of engineers in system administration and software development.
Throughout my career, learning has been my constant driver. Sharing my knowledge has always been just as important. My first conference talk was back in 1999 about the newly released PHP 3.0. Since then, I’ve given presentations at more than 100 different events ranging from local user group meetings to global conferences. As Local Track Chair, I also helped curating the DevOps Track at DrupalCon Europe 2013 in Prague.
Opsitive is my latest approach to sharing my expertise. By training and mentoring individuals as well as teams, I want to help DevOps practitioners collaborate more effectively and turn the great technologies we have at our disposal into personal and business success.
