At CGI Group, I lead Microsoft 365 architecture and support across concurrent enterprise client engagements. I delivered Copilot readiness and rollout for 5,000+ licensed users, and remediated oversharing across 1,200+ SharePoint sites ahead of enablement.
I executed a tenant-to-tenant migration of 8,000 mailboxes and 20 TB of SharePoint and OneDrive content across six waves, with zero unplanned business downtime. I also raised a client’s Microsoft Secure Score from 54% to 81% within two quarters.
At AT&T, I engineered Exchange Online and hybrid messaging for 40,000+ mailboxes and migrated 12,000+ mailboxes to Exchange Online. I implemented email authentication controls across 30+ corporate domains and helped reduce spoofed inbound volume by over 80%.
Earlier, at Molina Healthcare, I delivered a Teams rollout to 15,000+ users and built DLP policies for protected health and personal information. Across my roles, I’ve worked on Microsoft 365 messaging, identity, security, compliance, collaboration, and migrations in regulated environments.
