Gavin Francis
@gavinfrancis
Senior System Administrator specializing in secure Microsoft 365, Azure, and virtualization for reliable uptime.
What I'm looking for
I’m a results-driven Senior System Administrator with 7+ years of progressive experience architecting, securing, and optimizing enterprise IT environments. My deep expertise spans Microsoft 365 and Azure, Cisco/Fortinet network security, and VMware/Hyper-V virtualization, backed by CCNA certification and a consistent focus on reliability and security.
I’ve delivered measurable impact—an 87% reduction in security incidents through ISO 27001 controls, MFA enforcement, and vulnerability management, plus a 40% reduction in system downtime via automated monitoring and incident workflows. I also drive cost governance, including a 22% annual Azure cloud cost reduction through right-sizing and reserved instance strategy.
In my current role, I provide Tier-3 enterprise support for 500+ global users with 99.8% uptime, administer M365 and Entra ID for 1,000+ users, and manage 150+ VMs across VMware vSphere and Hyper-V with full DR readiness. I combine automation (PowerShell, Azure CLI), ITSM discipline (ITIL, ServiceNow), and security tooling (Microsoft Defender, Trellix EDR) to keep environments stable, compliant, and resilient.
