Message

I've supported Microsoft 365, identity, security, collaboration, messaging, and endpoint environments for more than 16 years, most recently building identity automation at Landis+Gyr.

At Landis+Gyr, I built PowerShell automation across five Active Directory and Entra ID domains and developed Microsoft Graph scripts for sign-in and audit-log analysis. I supported identity governance, access reviews, remediation, SOC 2 evidence collection, and cloud identity security controls.

Previously, I administered Microsoft 365 for 4,000+ users across 60+ locations at Fayette Heating & Air and TurnPoint Services, leading migrations and automating administration with PowerShell, Microsoft Graph, and Power Automate. I also bring hands-on experience with Entra ID, Conditional Access, MFA, SSO, Exchange Online, SharePoint Online, Teams, Purview, Defender, and endpoint management.
