I currently work for Microsoft as a Senior Premier Field Engineer specializing in Exchange.
My history is a Microsoft infrastructure architect/consultant/engineer who has worked with Exchange on an enterprise level since the 5.0 days, and AD since Windows 2000. I have experience with Hyper-V, Windows clustering, HA, DR, etc... and recently started learning Lync/Skype for Business.
Back in the day I used to program in PASCAL and Turbo C (long live WWIV!), so I have a good grasp on programming concepts and feel right at home with PowerShell and scripting in general.
