What I'm looking for

I'm looking to contribute to a security team where I can investigate incidents, improve detection and response workflows, apply threat intelligence, and continue growing in threat hunting, vulnerability management, and cybersecurity operations.

At Dell Canada, I monitor enterprise security alerts, endpoint telemetry, and threat indicators to identify incidents and support timely escalation. I investigate events across Splunk, CrowdStrike, Carbon Black, and Microsoft Defender for Endpoint, validating threats and documenting recommended response actions.

Previously at Zenith Bank, I triaged alerts in a regulated banking environment, investigated phishing, supported digital forensics, and coordinated containment activities. I also reviewed vulnerabilities, tracked remediation, and mapped attacker behavior to MITRE ATT&CK and the Cyber Kill Chain.

I bring practical security operations experience across incident response, threat intelligence, threat hunting, vulnerability assessment, and detection tuning. I focus on turning technical findings into clear investigation summaries, security reports, and operational recommendations.
