I support the GPU software stack for Intel Chromebooks.

I lead the Release Engineering team, whose responsibilities are building Gentoo's installation media and maintaining the infrastructure and tools used to do so. I also ported the distribution to MIPS' N32 and N64 ABIs and built installation media.I've been elected to four terms on the Gentoo Council, the governing body that makes technical decisions for the distribution.I maintain the Mesa and X11 packages, the GNOME desktop, and support odd architectures (Alpha and MIPS among others).
