Systems Administrator
- Manage 120+ Windows/Linux servers with a hybrid cloud vSphere Environment and over 3 petabytes of SAN Infrastructure.
- Onboarded the organization's entire server estate to Azure Arc, automating Connected Machine agent deployment through NinjaOne and applying an eight-class resource tagging taxonomy across Hyper-V clusters, standalone hosts, and VMware guests to scope policy, monitoring, and access control.
- Designed and implemented an update ring framework in Azure Update Manager, replacing manual per-host patching with tag-scoped maintenance configurations and phased pilot to production rollout, and deployed Windows Admin Center in the Azure portal to administer Arc-enabled servers without VPN, public IP, or inbound RDP exposure.
- Built an Azure RBAC model on role-assignable Entra ID security groups, scoping administrative access to least privilege and closing a privilege escalation path in the existing group structure.
- Built and administered a Hyper-V failover cluster with iSCSI shared storage on an IBM FlashSystem 5200, including MPIO configuration, Cluster Shared Volumes, and a File Share Witness, as part of an in-progress 10 Node VMware to Hyper-V infrastructure migration.
- Redesigned and relaunched the organization's Intune hybrid Entra join and Windows Autopilot process end to end, resolving a backlog of unmanaged and noncompliant devices and moving enrollment from a manual, admin-driven process to self-service for end users, including endpoint application deployment.
- Led an SSO migration for the Deltek Costpoint ERP system to Microsoft Entra ID across 4 separate environments ahead of a vendor-mandated deprecation of legacy database authentication, and rolled out SSO to 1000+ users across additional vendors (Adobe, Autodesk, SafetyCulture) including domain claim, just-in-time provisioning, and bulk migration of existing accounts to Federated ID.
- Manage the organization's Microsoft GCC High secure enclave, administering virtual desktops and physical endpoints through CuickTrac while ensuring secure CUI access, and own CMMC Level 2 compliance workstreams including System Security Plan and Customer Responsibility Matrix documentation and tabletop incident response testing against NIST SP 800-171.
