Strong PowerShell scripting, including the Microsoft Graph PowerShell SDK. Microsoft 365 tenant administration experience across core workloads. Demonstrated ability to harden a Microsoft 365 and Windows environment — Conditional Access, MFA enforcement, privileged access, endpoint compliance, and Defender policy — against real threats, not theoretical ones. Working knowledge of Windows Server, virtualization (vSphere preferred), and core networking. Demonstrated ability to plan and execute migrations affecting non-technical end users. Strongly Preferred Microsoft 365 Certified: Endpoint Administrator Associate, Identity and Access Administrator Associate, or equivalent demonstrable experience.
