I am a graduate of UC Berkeley with both a BA and MS in Computer Science. GO BEARS!
I currently work as a senior software engineer at Apple Inc., working primarily on the Embedded Simulator and related technologies. Prior to my role on the Embedded Simulator Team, I worked on the BSD and Darwin Runtime and Services in Apple's Core OS (Libc, Libsystem, etc).
In OSS-land, I am the maintainer of the XQuartz Project (X11 on OS X) and a maintainer of a number of ports in MacPorts, including X11 and clang.
