Summary
"I have over 6 years of experience working with Azure AD (Microsoft Entra ID). One of my key achievements was managing Azure AD Connect environments, including synchronization, health monitoring, and troubleshooting. I successfully supported Office 365 and Azure AD migration projects, integrated enterprise applications using SAML and OAuth-based SSO, and implemented Conditional Access and MFA policies to strengthen security. I also deployed Microsoft Defender for Identity, monitored security threats, managed RBAC permissions, and enabled Continuous Access Evaluation for real-time access control. These initiatives improved security, streamlined user access management, and ensured compliance across the organization."
