Build complete environments when the situation calls for it: Active Directory, DNS, DHCP, Group Policy, file and print services, firewall, VLANs, wireless, Microsoft 365 tenant, licensing, backup, and endpoint security, from bare hardware to a working site. Plan and execute infrastructure projects in phases: domain controller replacements, server migrations, network rebuilds, email migrations to Microsoft 365, and hardware refreshes, each with a cutover plan and a rollback path.
