Senior Microsoft 365 administrator specializing in Azure AD security, hybrid identity, and modern workplace compliance.
NigeriaWhat I'm looking for
I’m a results-driven Microsoft 365 Administrator with 15+ years of hands-on experience designing, deploying, and managing enterprise-scale M365 tenants, hybrid identity solutions, and security/compliance frameworks. I’m an expert in Azure AD, Conditional Access, Defender for Office 365, Intune, Teams governance, and mailbox migrations, with a strong focus on reducing security risks and enabling secure modern workplace adoption.
At Gigmos International Limited, I own Exchange Online hybrid administration as the primary escalation contact for critical incidents and on-call support, and I’ve led mailbox migrations from on-premises Exchange to Microsoft 365 with near-zero downtime and full data integrity. I design and enforce organization-wide security architecture using Defender for Office 365, Conditional Access, and MFA, automate admin tasks with PowerShell, and deploy Intune MDM/MAM policies with compliance enforcement, including Azure Information Protection labeling and policies.
