I work for Canonical as the Ubuntu Community Team Manager.
As an Open Source contributor, I am mostly involved in app development and localization: I'm the main developer of Qreator, I lead the Ubuntu Catalan Translators team and I'm also a GNOME translator. In the past I've been involved in the translation of other projects, such as Debian or Mozilla.
If you've got any question about translating Ubuntu, or creating apps for Ubuntu, you're at the right place ;-)
