Message

At TEAMLOGIC IT, I support multiple MSP client environments and troubleshoot endpoint, Microsoft 365, server, network, and security issues. I also serve as a senior escalation resource and work directly with clients to resolve technical problems.

I led client onboarding projects and planned Microsoft 365 migrations, including Google Workspace migrations and transitions from on-premises file services to SharePoint Online. I also developed Python-based SonicWall API tools to automate firewall configuration and repetitive administrative tasks.

At GALAXY ELECTRONICS, I upgraded server infrastructure to Windows Server 2022 and migrated legacy telephone services to 3CX VoIP. At CELERIUS, I administered multi-site Windows Server, Active Directory, Hyper-V, Exchange, and SQL environments.

Earlier, at TELECOMMUNICATION SYSTEMS INC. on the Maryland Department of Transportation Contract, I supported an enterprise environment of 10,000+ users and played a major role in the statewide migration from Novell NetWare to Microsoft Windows Server 2003 and Active Directory. My background also includes Tier 2/3 support, Microsoft 365, virtualization, networking, and infrastructure migrations.
