Jeremy has been a core Drupal contributor since early 2002. His hobby web site, KernelTrap.org, was the first online community to push Drupal to scale beyond its modest beginnings and to achieve popular recognition as a competitive CMS solution. Many of his patches have been merged into core, improving Drupal's caching layer, optimizing Drupal's bootstrap process, improving database queries, and generally improving Drupal's overall performance. He has given seminars on Drupal performance and scalability, both in person and over the Internet.
Tag1 Consulting, Inc was founded in 2007, focusing on continually improving the performance of Drupal powered websites. They have been publicly recognized by Drupal's creator as being among the very best at what they do. Tag1 takes the holistic approach to scalability which includes designing and improving the infrastructure, tuning the network and LAMP stack (including *BSD), optimizing existing code and database queries, integrating third party search solutions, and improving cache performance.
