System Architect, Percona
Daniel started making MySQL tools in 2004. At the time almost no MySQL tools existed publicly. In 2005 he created HackMySQL.com where he published tools and whitepapers about MySQL performance, query optimization, and internals. These were lessons learned from his previous job as a Unix sysadmin at a large datacenter. Daniel joined Percona in July 2008 to work on Maatkit, a suite of command-line tools for MySQL which is now Percona Toolkit. At the 2010 MySQL Conference & Expo, Daniel was named the Community Contributor of the Year for his work on Maatkit. Daniel currently leads web development at Percona, focusing on Percona Cloud Tools, a web app and service for MySQL performance management.
