Angestellt, Senior Automation Engineer, IONOS SE
I am a combination of a software developer (Golang, Java, Python, Perl, etc.) and a Linux system engineer who knows how to automate things, also under most paranoid security requirements. I like to combine skills that are seldom combined in one person both for fun and profit. I speak five human languages. Recruiters, please scroll down to "portfolio" section before sending me any nonsense.
