GlobalNET
At CivicActions, I was either lead or sole front end developer/themer on a number of federal and local government web sites. Unfortunately, many of these, such as GlobalNET, are password protected or intranets. I worked on GlobalNET for nearly two years, from initial UX design, through site building and theming phases. It is a fully responsive Drupal 7 site (based on he Zen base theme, and using Zen grids) with which I am proud to have been involved.
