About Me
Defending with precision
Security is not a product — it's a discipline built on vigilance, curiosity, and decisive action.

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
Achieving zero major non-conformities requires aligning policies, people, and processes well in advance — not just at audit time. Sustained compliance is a continuous discipline, not a one-time event.

How Tuned SIEM Alerts Transformed Incident Visibility by 35%
Alert fatigue is the enemy of effective SOC operations. Fewer, higher-fidelity alerts — carefully configured and regularly reviewed — dramatically improve detection speed and accuracy.

Reducing High-Risk Findings by 30% Through Continuous Assessment
Risk assessments are only as valuable as their follow-through. A structured cadence of identify → prioritize → remediate → verify keeps the threat surface steadily shrinking over time.
