An automatic vouch for being a Mozilla employee.
Leo has contributed to the Air Mozilla codebase.
I've known Leo for a long time and he has been active in several parts of the project, including being involved with supporting the launch of local Mozilla community sites. My favorite experience with Leo was working together to launch the Mozilla Antarctica community :)
