Hi, I'm Robert. I'm a Linux Engineer, open source enthusiast and a self-hosting geek. Most of the time I work in Operations and focus on infrastructure and deployment automation, which is my real passion. 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 started almost 10 years ago. For more than 5 years, maintaining and managing Linux servers in professional environments has been my daily business. I have worked a lot with Red Hat Enterprise Linux in corporate environments and prefer RPM-based distributions for my personal use as well. My daily driver is a Thinkpad powered by Fedora and since the restructuring of the CentOS project, I have been using Rocky Linux for my servers.

## Experience

**[ownCloud](https://owncloud.com/)**\

<--->

ownCloud is an open-source file sync, share and content collaboration software. As part of the operations team, I am responsible for the company-wide server infrastructure. That also including the Continuous Integration platform, which is a critical component for the development of our products. To manage the container-based deployments of more than 70 servers, we follow the infrastructure as code approach and use Terraform, Ansible and Continuous Deployment. Graylog, Telegraf, Prometheus and Grafana build the foundation for a seamless monitoring and troubleshooting.
