What I'm looking for

I’m looking for a role where I can support and secure Microsoft 365 (Exchange, Teams, identity, compliance), improve case workflows, and deliver great customer outcomes—while growing into cloud and web/UI work in a team that values quality and responsiveness.

I’m a Technical Support Engineer (M365 Concierge) supporting customers with secure, reliable Microsoft 365 experiences. I focus on Exchange Online, Microsoft Teams administration, and identity controls that keep users productive and protected.

I manage Exchange Online services end-to-end—mail & mail flow management, domains & DNS configuration, mailbox administration, and security/compliance through EOP and hybrid mail flow support. I also administer Teams with user & license management, channels configuration, messaging and meeting policies, and troubleshooting for voice and collaboration issues.

I strengthen the environment through identity and security fundamentals: MFA, conditional access policies, audit and sign-in logs, external collaboration settings, and cross-tenant synchronization. I further drive compliance outcomes with DLP, sensitivity labels, eDiscovery, Communication Compliance, Threat Explorer, Safe Attachments/Safe Links, and Defender for Office 365 policies—continuously improving Microsoft Secure Score.

I’m customer- and outcome-driven, consistently meeting CSAT goals, avoiding DSAT, and optimizing workflow to handle 90+ case intakes with fewer than 11 cases backlog and 2.0–3.0 days days-to-closure. I also bring teaching experience from NYSC, where I integrated technology into classroom lesson plans.
