IT Systems Administrator and Cloud Computing graduate from George Brown Polytechnic (GPA 3.55, May 2026) with 6+ years of experience owning complete IT environments across multi-site operations — 95%+ uptime, 35–40 tickets weekly at 95%+ first-contact resolution, and 40% reduction in manual IT overhead through PowerShell and Microsoft Graph API automation.
My work focuses on Microsoft 365 administration, identity and access management (Entra ID), endpoint security (Intune + Defender), cloud infrastructure (Azure + AWS), and AI-enabled IT automation. I build systems that are technically sound, operationally practical, and secure.
