I am a Lead Systems Architect at Appalachian State University.  The team I work for is known as Enterprise, Microsoft, Apple & Chrome OS Systems (EMACS) within the Central IT division.  You can read all the fun details at the bottom of this page, https://its.appstate.edu/about/central-it/infrastructure-and-systems.  My main focus areas currently are Azure Virtual Desktop, Azure Infrastructure, Azure Active Directory, Active Directory Domain Services, Active Directory Certificate Services, Microsoft Endpoint Configuration Manager, and various enterprise applications that run on Windows Server.  I also work with Office 365, but mainly licensing and client applications since we are a Google shop.
