About Me

Hi, I’m Robert. On my private blog I write about everything that comes to my mind, but mainly about topics from the Linux and open source world. I’m a Linux Engineer, open source enthusiast and a self-hosting geek.

My Linux journey began almost 10 years ago, for more than half of them maintaining and managing Linux server deployments in professional environments is my daily business.
