Cybersecurity Assurance & Architecture

About

Cybersecurity engineer currently specialising in security assurance at the University of Otago, based in Christchurch, New Zealand.

Formerly worked for Ember Technology, providing cybersecurity support to over 300 clients.

My work spans Microsoft Defender XDR, Sentinel, Entra ID, Conditional Access, Purview, and secure-by-design validation. I design, assess, and validate secure-by-design solutions across Microsoft 365 and Azure.

I work across both technical and business audiences, translating security risk into practical actions that improve real-world outcomes.

Background in infrastructure, systems, and client-facing technical roles, so my security advice is grounded in how environments actually run.

Focused on validating control effectiveness, identifying risk, and strengthening security posture.
