Chris

Chris started in computing and I.T. in the mid to late 1990's. After the dust had settled from Y2K, he found himself a bit more focused and working with database servers on the Unix platform. His first exposure to SQL Server was in 2007 and he has been working on that platform ever since. Chris is currently a Sr. SQL Server DBA in more of a DevOps role with a main focus on operational reliability, stability and performance. His specialty is automation. He truly enjoys the days he gets to spend building tools with PowerShell to help his fellow DBA's manage their ever growing SQL Server environment.
