Michal Ptaszek
ejabberd employer and deployer
Erlang Solutions

Michal fell in love with Erlang at first sight. He joined Erlang Solutions in 2008 and since then has been involved in a number of projects, mostly employing ejabberd to deliver non-trivial Internet Messaging services in various areas, like standard IM applications, social networks, banking, mobile applications and the gaming industry. He has been responsible for designing, extending and deploying ejabberd multi-million user clusters all over the world. He graduated from University of Science and Technology in 2010 with masters in Computer Science, doing his research on tools for distributed large-scale computing.

Refactoring and testing ejabberd XMPP server

ejabberd is an open source, scalable, extendible, cross-platform Jabber/XMPP server written in Erlang. During the last few years we have been involved in building and optimizing a number of projects integrating ejabberd server with various subsystems; starting from regular IMs, going through social networks, banking, online gaming and finishing with mobile applications. Basing on that experience we introduced a set of refactorings applied to ejabberd sources, as well as code optimizations, giving the machines hosting ejabberd significant RAM savings. I will also describe escalus framework, which can be used for blackbox testing of XMPP servers. At ESL we developed test suites based on it, which covers some Jabber RFCs and can be used for regression testing when XMPP server is being refactored.
