Greg caught the technology bug as a teen while playing with 300-baud modems, bulletin boards, and hacking Pascal and BASIC on a TRS-80.

After a foray into live television, he has been working professionally on telecommunications infrastructure and system administration since 1996. He joined the OSU Open Source Lab in 2006 where he engineered and managed a large online learning infrastructure and worked with many large open source projects including Apache.org, Kernel.org, and Drupal.org.

Károly Négyesi, better known in Drupal circles as ChX, has been a Drupal core contributor since 2004. He contributed more patches to core than anyone else and consequently maintains the most core subsystems -- no less than seven. He was the first leader of the security team and is on the team ever since. After scaling NowPublic.com to a Top 500 site by constructing one of the first Drupal-CDN integrations, he met his first real scalability challenge by architecting SCAN, a predictive newsdesk tool for discovering news events before they become mainstream and then following them using sources like Twitter and CNN. For SCAN, he was using MongoDB, a NoSQL database, before the word NoSQL even existed. He was the senior software architect for the re-launched Examiner.com, one of the largest Drupal sites which also based on MongoDB.

Rudy Grigar was introduced to the Drupal project through the Oregon State University Open Source Lab where he worked as a systems administrator and database administrator.  At the OSL he rebuilt and expanded the caching infrastructure using Varnish and Memcached.  He also managed their MySQL and PostgreSQL databases and migrated hosted Drupal websites to an optimized stack built from Pressflow, Varnish, memcached, and APC.  

Rudy continues to work closely with Drupal as a maintainer of the drupal.org infrastructure, providing support for backend and development services.  More recently he worked on the drupal.org redesign launch and has helped various clients successfully launch or tune their websites as Director of Operations at Tag1.
