Information Security Analyst at Transitus Business Development Services, leading incident response and threat investigations.

Trinidad and Tobago
Message

At Transitus Business Development Services, I lead a team of four in threat triage, security investigations, proactive threat hunting, and response coordination. I also direct endpoint and network threat monitoring, SentinelOne investigations, and analyst handovers.

Through security monitoring, incident management, and operational follow-up, I helped maintain approximately 99% uptime of supported services and systems. I coordinate endpoint security workflows across Windows, macOS, and Linux.

In my selected cybersecurity work, I developed and documented MITRE ATT&CK-aligned threat-detection queries and standardized incident-response procedures. I also conducted vulnerability and risk assessments, prioritized remediation actions, and prepared technical and business-facing reports.

I deployed and administered SentinelOne endpoint agents and investigated process, file, and network telemetry using Deep Visibility and Storyline correlation. My background includes an MSc in Cybersecurity with Distinction, postgraduate research into AI/ML applications in SOAR, and more than 10 software application projects with secure development considerations.
