About Me

Defending with precision

Security is not a product — it's a discipline built on vigilance, curiosity, and decisive action.

With a background in Networks and Communication Systems and hands-on experience as an Information Security Officer at a financial institution, I specialize in threat detection, SIEM implementation, risk assessment, and regulatory compliance.

Currently completing a Cybersecurity Graduate Certificate at Durham College (Oshawa, Ontario), graduating June 2026. Open to full-time cybersecurity roles across Canada.

Zero Non-Conformities: A Framework for Audit Readiness

Threat Detection · SIEM
