Hi, I'm Christian, located in Karlsruhe, Germany.
I'm interested in software system design, implementation and operation.
I believe that we are obliged to build software systems that are debuggable, reliable and correct, and that good programming languages and tools can help us pursue that goal.

My open-source activity is mostly in the OpenZFS sphere:

• I develop and maintain zrepl a one-stop solution for ZFS backup & replication that aims to be more maintainable, smarter at error handling and ZFS feature support than the usual shell script, and most importantly correct.
• I am also involved in the OpenZFS community: I attend most leadership meetings and occasionally contribute code to the project.
