// about

5+ years keeping client environments healthy at an MSP.

At The Computer Guy, Inc., I support Windows Server, Active Directory, and Microsoft 365/Azure for clients across many industries. I design Conditional Access and MFA, deploy Azure Virtual Desktop, run AD migrations, and harden domains with tiered admin models. I also manage the VLANs, VPNs, and firewalls behind it all.
