About Me

Building the bridge between IT operations and security

From IT Support to Cybersecurity

As an IT Support Engineer II at Siepe, I administer Microsoft 365 tenants across 50+ companies, manage Active Directory and Microsoft Entra ID (including Conditional Access policies), and deploy and secure endpoints through Microsoft Intune. I'm channeling that technical foundation into cybersecurity, where I can focus on protecting the very systems I've learned to understand so well.

My hands-on experience with enterprise systems, cloud infrastructure (Azure/AWS), and network security tools like Cisco Meraki and Cisco Umbrella provides a unique perspective on security vulnerabilities and defensive strategies.
