I am a Systems and Information Technology Engineer specializing in networks, telecommunications, cloud support, and enterprise technical support. I have more than five years of experience helping users and organizations resolve complex issues across computer systems, networks, hardware, and Microsoft cloud environments.
I specialize in Microsoft 365 administration and Microsoft Entra ID identity services, including Exchange Online, SharePoint Online, Teams, OneDrive for Business, licensing, provisioning, and tenant administration. I am experienced in managing authentication, authorization, identity lifecycle, and access-control scenarios in enterprise environments.
I work extensively with hybrid identity technologies, including Microsoft Entra Connect Sync, Cloud Sync, on-premises Active Directory integration, Password Hash Synchronization, Pass-through Authentication, federation, and Seamless Single Sign-On. I troubleshoot synchronization conflicts, attribute mismatches, UPN and ImmutableID issues, provisioning failures, and directory object matching.
I use PowerShell and Microsoft Graph API to automate Microsoft 365 administrative tasks, reporting, and identity management operations. My security-focused experience includes Conditional Access, Multi-Factor Authentication, Self-Service Password Reset, Zero Trust practices, sign-in log analysis, audit log review, and authentication-flow troubleshooting.

I collaborate with escalation engineers, product teams, and customers to investigate critical incidents, perform root cause analysis, and provide practical technical recommendations for enterprise cloud and identity environments.
