linux/unix system engineering & consulting


I have more than 10 years of professional experience as a System Administrator/Engineer. See my resumé and some of my code examples.

I am specialized in infrastructure automation, orchestration, monitoring and tool development for unix/linux based systems.

Feel free to contact me if you're interested in my work. (Gulp Profile in german)

Here's an overview of things I'm good at. I’ve used all of the following technologies in production environments for some years. Still I’m constantly striving to improve running systems and use new technologies where applicable.
