Infrastructure Architect and Cloud Consultant delivering secure hybrid cloud architectures at scale.
IrelandWhat I'm looking for
I’m an Infrastructure Architect and Cloud Consultant with 16 years of experience across enterprise and public-sector environments. Currently, I’m embedded via Ernst & Young (EY) at the Irish Ministry of Agriculture, with full ownership of the hybrid infrastructure stack across on-premises, Azure, and VMware.
I lead architecture governance and design review, ensuring solutions align with security and regulatory requirements. My focus spans hybrid identity (Entra ID/Active Directory, SSO, SAML, RBAC, Conditional Access), server modernization, and endpoint management standards using Intune, SCCM/ConfigMgr, and MDT.
I also architect and validate infrastructure for resilience and compliance, including DFS/file server services, monitoring with Azure Monitor and Datadog, and DR/BCP planning. I bring strong operational and delivery strength from DevOps automation (Terraform, PowerShell, ARM, Bicep, CI/CD governance, AWS SSM) and from previous technical escalation and cloud support experience.
