Hi, I am Mario

Mario Kleinsasser

Team Leader Cloud Operations at STRABAG BRVZ

Hi! I am Mario! For more than 20 years I am working as IT-engineer. After my apprenticeship, I entered the IT business as a newcomer. Several years later I passed my B.Sc. and M.A. studies, both with distinction. Since 2018 I am speaking at conferences and I am blogging to share my knowledge with others. As a team leader and cloud architect, I have the opportunity to work with different technologies, within different environments. My motto is: “Imagination is more important than knowledge because knowledge is limited”. After all, you can achieve anything if you believe in it.

Podman: Container ohne Daemon und Root-Rechte
