Senior Directory/Groupware administrator for all things related to Office 365 and Azure, including on-prem Exchange, Active Directory, SSO Integration, and the enterprise e-mail security gateway for over 15,000 people. I work with a team that manages thousands of Windows servers spread across over 1000 locations as well as the cloud. I am also directly responsible for parts of our Linux infrastructure such as our Enterprise DNS and E-mail clusters. I work in a highly virtualized environment with management knowledge of both VMware vSphere and Hyper-V. In addition, I am responsible for our data center load balancers. I recently completed a complex F5 Viprion hardware and operating system upgrade in our data centers, bringing them forward several versions to the current release.PowerShell scripting for automation and management is something that I consider is essential for an environment of this size. I have written a large number of scripts for managing Active Directory, Windows Servers, and Exchange/Office 365 for both myself, my team, and other teams to utilize.I am considered to be one of the go-to people by other teams for challenging issues due to a broad area of technical knowledge and am considered by many to be the final escalation for problems. I frequently work hand in hand with other teams to bring their projects and my own team's projects to successful completion.
