I automate secure Microsoft 365, endpoint, cloud, and network operations across complex environments.

At Science UK, I administer Microsoft 365 and Entra ID, manage Intune/Autopilot and Jamf Pro for around 2,000 endpoints, and automate provisioning to reduce enrollment failures by about 30%. I also lead remote, multi-tenant incident management in ServiceNow, maintaining roughly 75% first-contact resolution while resolving high-impact identity, network, and cloud issues before SLA breaches.

I've delivered Azure Virtual Desktop improvements, PowerShell and API automation, Azure CI/CD pipelines, Exchange recovery, and AWS infrastructure troubleshooting across Science UK, Markerstudy Insurance Services, NHS/Barts, and Team ITG. I bring hands-on experience in Microsoft 365, Azure, AWS, networking, endpoint security, and customer-facing technical support.
