Message

At PRESENCE MARKETING, I lead a four-to-one Microsoft 365 tenant consolidation across Exchange, OneDrive, SharePoint, Teams, identity, and endpoints. The work includes phased migrations, preflight validation, cutovers, and PowerShell tooling.

I strengthen identity and security across Microsoft 365 and Azure, including Entra ID controls, endpoint compliance, and email protection. I also build PowerShell, Microsoft Graph, and PnP automation for administration, migrations, and reporting.

At TERRANA GROUP LLC, I own technology strategy and day-to-day IT operations for a nationally distributed business. In independent projects, I build and maintain applications and self-hosted infrastructure, including a finance platform with offline OCR processing and a job-search PWA.
