Most companies don't discover their M365 security gaps until after a breach - or a compliance audit. I've supported and secured enterprise environments spanning healthcare and financial services - including a 16,000+ user financial institution and a 12,000+ user healthcare organization - where security failures have real business consequences. I'm a Microsoft 365 and IAM Security Engineer with 6+ years of hands-on enterprise experience across cloud and on-premises environments. My work focuses on identity security, endpoint management, secure mobile access, and compliance-aligned Office 365 architecture. I don't just secure environments - I build scalable systems that improve operational efficiency, strengthen access governance, and support modern remote and BYOD workforces without sacrificing usability.
