Systems administrator specializing in Microsoft 365, SharePoint Online, and identity access management—delivering secure, reliable tenant support.
What I'm looking for
I’m a Systems Administrator with four years of progressive MSP experience administering and supporting Microsoft 365 commercial environments across multiple client organizations. I bring hands-on strength in Microsoft Entra ID, Exchange Online, SharePoint Online, Microsoft Teams, OneDrive, Intune, and end-to-end user and group lifecycle, permissions, licensing, MFA, and Conditional Access.
I’m especially effective at resolving SharePoint and Teams access issues, coordinating approved changes with business stakeholders, and documenting technical workflows to improve handoffs and troubleshooting. I support onboarding/offboarding, provisioning/deprovisioning, access reviews, and hybrid identity activities involving Azure AD Connect and authentication alignment.
I also focus on security, least-privilege practices, and investigation readiness—using Microsoft Defender and Microsoft Purview audit information, with eDiscovery support and suspicious-activity investigation. Through PowerShell and RMM-based automation, I build repeatable administration and remediation workflows, and I’ve supported multiple go-live and acquisition transitions with post-change stabilization.
