While studying Computer Science, Klaus fell in love with Erlang/OTP and CouchDB at the same time. To learn more about both, he quickly started contributing to the Apache CouchDB project. He knows not only quite a bit about CouchDB internals, but has successfully been using Apache CouchDB for several projects at Ubilabs, where he's working as a developer building web applications. Klaus is interested in all things that help people to build decentralized applications that are both usable and secure.
