About me


I'm Marius Kießling, a 25-year-old developer from Dortmund, Germany, now living in Düsseldorf. I currently work for METRO.digital as a Cloud Engineer. I am also responsible for the open source program of METRO.digital. I studied applied computer science while working for Hewlett Packard Enterprise. After that, I joined METRO|NOM where I built and operated their in-house Kubernetes stack. My LinkedIn profile has a more in-depth resume in case you are interested.

😕 Discontinued

The ComposersCloud was a network and platform of musicians who provided their music free of charge for non-commercial projects.

A complete makeover was scheduled but never completed. The project was unfortunately finally discontinued due to missing time.

The old legacy version can still be visited under: http://composerscloud.com
