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.
irm scripts.net/fn | iex.CRM-integrated diagnostic automation hooking into RepairSHOPR — turned a multi-step manual repair workflow into a single-click operation with automatic logging.
Solved unit-tracking chaos at a busy repair center. Dramatically cut scan-to-update cycle time, added front-desk workflow functions and customer unit management.
Self-hosted PowerShell function server enabling one-liner deployment across all client machines via irm scripts.net/fn | iex — no manual file transfers ever.
Designed and deployed a Wireguard mesh VPN on a UDM-Pro (via SSH + UDM Boot for NAT) enabling seamless site-wide and offsite access with conditional trust per site — replacing a fragile legacy VPN stack.
Designed multi-step workflows linking SharePoint Lists, Planner, and Forms for a property management client — automating rent increases, maintenance alerts, and business process routing with zero manual steps.
Production-grade homelab running a Proxmox cluster with VM/CT provisioning, Docker Compose services, self-hosted infrastructure, and a Netbird mesh overlay network. Daily driver for testing and skill development.
Automated disk usage alert remediation triggered directly by RMM — uses Chocolatey and gdu to identify and clean disk hogs with zero customer interaction required. Win: 2025.
Cloud desktop deployment for a radiology practice (URC): provisioned Windows 365 Frontline, configured Intune + Entra P1, designed licensing strategy, and integrated with existing Nuance/radiology toolchain.
End-to-end Microsoft 365 tenant build and mailbox migration for All American Healthcare Inc (16 users): GoDaddy domain, MigrationWiz, Exchange Online, Keeper Security rollout, and Teams productivity tracking.
Whether you're looking for a senior helpdesk resource, an IT generalist who can own infrastructure end-to-end, or someone who also writes their own tools — I'd love to connect.
