Hi, I'm Robert. I'm a Linux Engineer, open source enthusiast and a self-hosting geek. Most of the time I work in Ops and focus on infrastructure and deployment automation. On my private blog [thegeeklab.de](https://thegeeklab.de/) I write about everything that comes to my mind, but mainly about topics from the Linux and open source world.
My Linux journey began almost 10 years ago, for more than half of them maintaining and managing Linux servers in professional environments is my daily business. I have worked with Red Hat Enterprise Linux in corporate environments and got used to it. I also personally prefer RPM-based distributions and therefore also use Feorda and after the restructuring of CentOS I switched to Rocky Linux on my servers.
ownCloud is an open-source file sync, share and content collaboration software. As a System Administrator at ownCloud I'm responsible for the operation and availability of the company infrastructure. That also including the Continuous Integration platform based on Drone CI which is a fundamental component for the development of our products.

The Schwarz IT is the central IT service provider of the Schwarz Group where the main customers are the two retail divisions Lidl and Kaufland. During my work as part of the Linux Server team, one challenge was to design a test-driven infrastructure environment using Ansible and Ansible Tower for more than 4.000 Linux servers in three different data centers to replace the existing Puppet configuration management.

While working in the First Level Support Team of the Kaufland distribution center of Barsinghausen, the main task was to provide support for all problems related to the soft- and hardware environment of the employees and the retail ERP solution (SAP).
During my dual studies, I worked in various areas at Schwarz IT. After joining the SAP security department, I worked in the Linux department, where I also wrote my Bachelor Thesis entitled "Selection and prototypical implementation of a configuration management solution for Linux".
