What I'm looking for

I seek a security role where I can lead incident detection and response, improve cloud and insider-risk controls, apply frameworks (ISO/NIST), and work collaboratively in fast-paced environments for measurable security outcomes.

I am a detail-oriented Information Security and Cybersecurity specialist with over eight years of global experience across consulting, financial services, aviation, and energy. I focus on delivering secure, compliant, and resilient systems through pragmatic risk management and technical controls.

My background spans SOC operations, incident response, penetration testing, vulnerability management, and insider risk detection, with hands-on experience in cloud security for AWS, Azure, and GCP. I have applied frameworks such as ISO 27001, NIST, DORA, and methodologies like MITRE ATT&CK and OWASP Top 10 to strengthen defenses.

I have led programs and projects including insider risk management, ProofPoint DLP rule development, enterprise risk assessments, internal audits, and SIEM detection engineering. I combine technical tool expertise (Splunk, Nessus, Burp Suite, Qualys, CrowdStrike, Wiz) with stakeholder management to drive measurable security improvements.

I hold an MSc in Cybersecurity (Distinction) and certifications including CEH and ECSA, and I seek to apply my investigative, automation, and cloud security skills to help organizations reduce risk, improve detection, and build resilient security programs.
