Jeff is a Partner and CIO at Tag1 Consulting where he works with clients of all sizes to create and maintain secure, automated, and high performance server infrastructures. A proponent of configuration management systems before Chef and Puppet existed, he leverages those and other tools to quickly deploy scalable infrastructures to support high traffic websites and applications.

Jeff has extensive experience with all aspects of open source software, gained over the years. As Operations Manager at Oregon State University’s Open Source Lab -- the largest open source hosting infrastructure of its kind -- he led the infrastructure and development teams. While there, Jeff coordinated with private corporations, government agencies, and nonprofits to help them understand open source licensing, development processes, and to get the most benefit from open source software. He has been involved in the CentOS Linux build and release process as a member of the QA team, co-authored the O'Reilly High Performance Drupal book, and works as a volunteer for the Drupal.org infrastructure team.

You'll likely find Jeff riding his bike around Fort Collins, possibly pulling a trailer holding his son, Luke.

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.
