👋 Hello, I'm
Sam Ludwig
Infrastructure & M365 Engineer — keeping 660,000+ users online with 99.9% uptime. PowerShell automator. SharePoint whisperer. Melbourne-based.
About Me
I'm an Infrastructure and M365 Engineer with 7+ years bridging physical infrastructure and large-scale cloud environments. Trusted by Victoria Police, Transurban, and the Department of Education to manage complex infrastructure and drive automation-focused outcomes.
Specialist in Microsoft 365 (Exchange, Intune, SharePoint, Teams, Entra ID), PowerShell automation, and endpoint management across environments supporting 660,000+ users. Proven ability to resolve critical L3 escalations, engineer compliance solutions, and deliver enterprise projects from deployment through to post-incident review.
Based in Melbourne's eastern suburbs. Australian citizen. When I'm not automating things, you'll find me on my bike — currently deep into Di2 derailleurs and Strava segments.

Case Studies
Real projects with measurable outcomes. The best way to evaluate what I can deliver.
Southern Hemisphere's Largest SharePoint Farm
Department of Education Victoria · Capgemini
The Challenge
Managing the largest SharePoint farm in the Southern Hemisphere — 660,000+ users across 1,000+ sites — with zero tolerance for downtime. The environment required 24/7 monitoring, complex cross-tenant governance, and compliance with Victorian government security frameworks including ACSC Essential 8.
My Role
Ultimate Tier-3 escalation point and senior engineer responsible for the SharePoint Online, Exchange Hybrid, Teams, and Google Workspace environments. Single point of accountability for all major incidents affecting 660K+ users.
Key Outcomes
Hospital Windows 11 Migration — Zero Patient Disruption
St John of God Health Care · 2023
The Challenge
Migrate 100+ clinical endpoints from Windows 10 to Windows 11 in a live hospital environment. No downtime. No disruption to patient care. EMR systems, diagnostic tools, and medical devices all had to remain operational. Any failure could directly impact clinical workflows and patient outcomes.
My Role
Lead endpoint migration engineer. Responsible for hardware preparation, Autopilot enrolment, Intune policy configuration, deployment validation, and hypercare support. Primary liaison between clinical end-users and the engineering team.
Key Outcomes
Automation Pipeline — Cutting Migration Processing by 87%
Knosys (GreenOrbit) · Cotton On, Harvey Norman, Healthscope
The Challenge
Intranet migration processing took 2 hours per migration — entirely manual, error-prone, and a bottleneck for the entire delivery pipeline. The process required data extraction, transformation, validation, and loading across multiple client environments.
My Role
Application Support Engineer delivering L3 support and automation for the GreenOrbit intranet platform. Responsible for maintaining 95% SLA resolution across major clients including Cotton On, Harvey Norman, and Healthscope.
