Message

At 21st Century Home Health Services, I lead day-to-day IT operations and technical support for 600+ employees. I planned and led the organization-wide migration from Google Workspace to Microsoft 365, coordinating the technical work, user readiness, and post-migration support.

I also built a centralized IT ticketing workflow in Monday.com and designed automation with Azure Automation, Microsoft Graph, and PowerShell. At Clarke Consulting, I managed a three-person IT support team and worked hands-on across client networking, servers, endpoints, and account access.
