I am an experienced system engineer with a strong background in Windows Server, Active Directory, networking, Hyper-V clustering, SAN storage, modern workplace solutions, and O365 migrations. Over the years I’ve worked with environments ranging from small businesses to enterprise-grade infrastructures.
