About

I'm a Microsoft 365 Engineer with 3+ years of enterprise experience keeping collaboration, identity, and security running smoothly across Exchange Online, SharePoint Online, and Entra ID. My day-to-day goes beyond ticket resolution, I build automations using PowerShell and Microsoft Graph API that cut manual work, tighten access governance, and scale across large user bases. I've led email security investigations, managed SharePoint modernisation migrations, and designed a fully automated identity onboarding system using Power Automate and Graph API that takes user provisioning from hours to minutes. What I work with: • Microsoft 365: Exchange Online, SharePoint Online, Teams, OneDrive • Identity & Security: Entra ID, Conditional Access, App Registrations • Automation: PowerShell, Graph API, Power Automate • Security & Compliance: Microsoft Defender, Purview, Audit Logs • Tools: ShareGate, ServiceNow, Rubrik, Azure, SendGrid, PowerShell Certified: • AZ-104: Microsoft Azure Administrator • AWS Gen AI Essentials • MS-102: Microsoft 365 Administrator Expert (in progress) I'm actively exploring M365 Engineer and M365 Architect opportunities where I can bring both hands-on admin depth and a strong automation mindset to a forward-thinking team. Feel free to connect or reach out, always happy to talk M365.
