I work at Red Hat on the systems management team. In addition to my work on company stuff, I also am a committer to Puppet and the maintainer of the 2.7 branch, manage the Erlang/Ruby/Nagios stacks, several early cloud guest initialization tools, and various other packages in EPEL/Fedora
I worked on building infrastructure for a number of startups before joining Red Hat, including Digg.com, Venmo, Acquia, and several others.
