Will it scale? This is the guiding question for Pantheon CTO David Strauss, whose all-for-one-and-one-for-all improvements to the Drupal infrastructure have made the largest Drupal websites in the world more scalable and secure, while saving developers thousands of hours in manual updates. If you've ever deployed an enterprise Drupal website, chances are you've benefited from one of the tools he's developed. After co-founding Four Kitchens, a successful Drupal development shop, David found himself gravitating away from custom client work and toward infrastructure solutions. Large clients like Creative Commons, Internet Archive, The Economist, and Wikimedia had already benefited from his scalability and database optimization work. Now he wanted to use this expertise to improve Drupal websites for everyone. When the opportunity to build an all-in-one Drupal platform came along, he knew he needed to be a part of it. In addition to his role as Pantheon CTO, David also serves on the Advisory Board for the Drupal Association, contributes to the infrastructure and security teams at Drupal.org, co-maintains the systemd/udev layer that runs on most of the world's Linux systems, and leads the development of Pressflow.
