Before leading a project on Google+, I helped design and build the Google Wave Realtime Search infrastructure. I also represented Google on several Java expert groups and created Guice Servlet, which dispatches nearly every pageview of Google's Java apps (Gmail, Blogger, Apps, Adwords, etc.).
I have also written books on Software engineering and regularly contribute to open source projects.
