Ezra Barnett Gildesgame is the Technical Lead of Acquia's Distribution Team. He is in charge of maintaining and developing Acquia's two distributions, COD (Conference Organizing Distribution) and Commons, the social business and collaboration distro. (Download them here: https://www.acquia.com/downloads.) His work goes into maintaining and improving these two Drupal products. The direct improvements made to the code go back to the repositories on Drupal.org, of course, but Ezra's work also helps the Drupal product landscape by helping other people working on other distributions.
