Joern has been developing, debugging and designing software for many clients. At kreuzwerker he is responsible for architecture, new technologies and concepts. A computer science graduate, his professional interest is in the use of functional programming languages and the architecture of distributed applications. In his diverse projects he has gained solid experience with operating systems (primarily Linux and Mac OS) and has created various databases from different paradigms. He masters C, Ruby, Java, Erlang and a little JVM LISP. He is thus as much at home in infrastructure and service clouds (preferably AWS) as on the command line. Joern is managing all DevOps, AWS and New Relic services at kreuzwerker.
When not working, he is most likely practicing Eastern martial arts.
