I'm Joseph Rosenbaum — a Senior IT & Systems professional based in Dallas, TX with over a decade of experience spanning enterprise helpdesk, MSP operations, network infrastructure, cloud administration, VoIP deployment, and custom scripting & automation.

My career started on the bench at PC ASAP writing AutoIT tools to automate PC diagnostics. Since then I've grown into roles supporting complex Windows/AD/Azure environments, managing O365 tenants, deploying Citrix VDI, configuring SonicWall & HPE networking, and onboarding & migrating full Microsoft tenants for clients like AAHC Inc. and URC.

Outside client work I run a production-grade homelab on Proxmox with Docker, self-hosted services, and a Netbird/Wireguard mesh VPN deployed on a UDM-Pro. I build Power Automate workflows, host PowerShell function servers for irm-based one-liners, and document everything in Obsidian.
