What I'm looking for

I’m returning to a full-time systems administration role in Ireland.

At Umbrella Infotech, I owned and operated an IT managed-services and consulting business supporting over 50 business clients. I administered Microsoft 365 environments and delivered infrastructure installations and migrations, from assessment and testing through documentation and handover.

At The Siemon Company, I developed PowerShell and Bash automation that reduced account provisioning time by approximately 75%. Earlier, at 17a-4 Compliance Software and Services, I completed more than 100 enterprise software installations and migrations; I’m now developing my skills through a home lab migration from Active Directory to a cloud-only Microsoft 365 environment.
