About me

Who am I

My name is Achim Nierbeck
I live in Karlsruhe Germany and I’m a former Senior IT Consultant (also Scrum Master), now branch manager at codecentric in Karlsruhe.


In my pre-management positions, I’ve worked on different open source projects. OPS4J Pax-Web (OSGi ready web container environment) and Apache Karaf. Since 2014 I’m a member of the Apache Software Foundation.

Open Source

I’m a strong believer in open source and therefore support it.
Right now I’m a committer and PMC at the Apache Karaf Project and comitter of the OPS4j Pax Web Project. where I also toke over the Project lead since it was kind of abandoned. Since May 2014 I’m a member of the Apache Software Foundation.


When I started to work for PTV 2006 I was part of a great Scrum Dev team where I learned a lot about Scrum. It even turned out for me to be a Scrum Master and I got my certificate in 2009.
