About
I am a systems administrator with 7+ years running Microsoft 365, Entra ID, Active Directory and Windows Server environments across healthcare, financial services, environmental services and retail in Canada and India.
I have delivered a full tenant-to-tenant Exchange Online migration for a joint-venture separation, a Pan-India laptop migration over a single planned weekend, and a Windows 11 rollout to 300+ endpoints in a PHIPA-regulated organization. I pair hands-on infrastructure engineering with strong service delivery, documentation and escalation management.
