I am an IT Systems and Network Administrator with more than 10 years of hands-on experience working with Windows and Microsoft technologies.

Today I manage a Microsoft 365 environment for over 300 users, including Microsoft 365 E5, Enterprise Mobility + Security E5, Microsoft Defender for Endpoint, Microsoft Defender for Cloud Apps, Microsoft Entra ID P2 and Microsoft 365 Business Premium. My daily work covers identity and access management, endpoint management with Intune, security hardening, and incident response.

Over the years I have designed, deployed and maintained Windows client and server environments, migrated organizations to Microsoft 365, and improved their security posture using tools like Conditional Access, device compliance, Defender XDR, and advanced auditing.

Because I live in these technologies every day, my teaching style is practical and exam-focused. On Udemy I create high-quality practice tests and training materials for certifications such as MD-102, MS-102, AZ-900, AZ-104 and SC-300, helping students prepare with realistic scenarios instead of memorizing brain dumps.
