Activities

I'm on the team responsible for deploying our University's central Linux servers and operating most services running on them. As a side project, I operate an instant messaging service together with Daniel Gultsch, the author of the Android client Conversations. In my spare time, I'm currently working on:

• The ejabberd XMPP/SIP/MQTT server.
• The eturnal STUN/TURN server.

I've authored various pieces of software and contributed to a wide viarity of open source projects, including the following:

• The Erlang/OTP language.
• The Erlang/Elixir TLS library.
• The Erlang/Elixir XMPP library.
• The MCabber XMPP client.
• The ngx_http_upload module for Nginx.
• The Monitoring Plugins for Icinga/Nagios.
• The NSCA-ng daemon for submitting monitoring results.
• The Bcfg2 configuration management system.
• The OSBF-Lua text classification and spam filter module.
• The Git version control system.
• The Mutt E-Mail client.
• The C99-snprintf library.
• The pGina credential provider for Microsoft Windows clients.
• The RADIUS Plugin for pGina.
• The Cyrus2Dovecot tool for migrating from Cyrus to Dovecot.
• The ZEDAT UPS Daemon (ZUPS) for UPS monitoring.

Apart from that, I coach a kids team at the best soccer club of all time.
