I'm a Free Software Developer working as a Principal Software Engineer at Red Hat on Samba and MIT Kerberos.

I'm a member of the international Samba Core Team. In my spare time and partly in my worktime I also work on libssh, a library implementing the SSH/SFTP protocol. I'm the maintainer of the lightweight unit testing framework for C with mock support named cmocka. I develop and maintain the cwrap project, a set to of tools for client and server testing. I've also developed the two-way file synchronizer csync. It is used by nextcloud/ownCloud as the desktop client sync engine.
