I am heavily involved in maintaining and evolving the current (Maverick) kernel, specialising mainly on the ARM architecture. Working with OEMs (Original Equipment Manufacturers) and community members alike, I spend a great deal of time conversing with our user base attempting to discover deficiencies in Ubuntu, then finding ways to fix them. Most of my time is devoted to bugs however. == Contact information == || '''Name''' || Lee Jones || || '''Email''' || lee.jones@canonical.com || || '''IRC''' || lag || || '''Launchpad''' || https://launchpad.net/~lag/ || || '''Blog''' || http://voices.canonical.com/lee.jones/|| == Ubuntu Contributions == === Maverick Development === I've been working at Canonical for the entire life cycle of Maverick, as a consequence I've placed a significant amount of work into it.

I have had the pleasure of supporting Ubuntu on the latest and greatest OMAP3 (Beagle) and OMAP4 (Panda) boards. Some of the drivers I have worked with (debugged) include; USB, Networking, MMC/SD, Audio, HDMI and Suspend/Resume. My most significant work on Maverick was working with TI on the HDMI video subsystem.
