I currently work full time on Mahara for Catalyst IT.
My review history can be found here
- The resizeimagesonupload gerrit tag is a set of patches for a recent notable review I've done.
- Another reasonably notable review was the plugin disabling change.
The full list of my released changes are found here on launchpad
Notable features/fixes I've implemented
- reverse ssl proxy support
- Fixing up a loophole in the quota calculation
- PHP5.4 compatibility
- The RSS XSS bug
- I've also done a lot of maintenance on embedded media things like google apps, etc.
I've done release tasks for 1.4.1 onwards, including getting patches into Ubuntu and Debian.
Other Mahara stuff
I've been working on a automated sphinx-based setup for the Mahara Manual that will swap the images out for localised versions, as well as automatically fetch the translations from launchpad.
