What I'm looking for

I’m looking for a role where I can strengthen SOC performance and detection engineering through MXDR/SIEM tuning, drive incident response impact, and support ISO 27001/PCI DSS readiness—working with technical teams and senior stakeholders to deliver measurable outcomes.

I’m a cybersecurity professional with experience in MXDR and SOC operations, incident response, detection tuning, vulnerability management, security awareness, and governance, risk, and compliance. I focus on triaging complex events, strengthening detection content, and translating technical findings for senior stakeholders.

In my current role as a Cyber Security Consultant (MXDR-Level 2) at BUI, I lead escalated alert triage and coordinate response across analysts and incident stakeholders during critical security events. I tune and refine detection use cases to align with current threat activity, investigate malware indicators through deep traffic analysis, and mentor junior analysts as a technical escalation point.

I’ve also supported ISO 27001 and PCI DSS readiness through governance, risk, and compliance reporting, internal review activities, and incident support with an emphasis on reducing operational disruption and strengthening response posture. Alongside this, I’ve delivered phishing simulations and security awareness sessions, and supported vulnerability scanning and the deployment of security technologies including DLP, SIEM, and WAF.

Previously at Guaranty Trust Bank, I responded to security events and helped reduce incident resolution time by up to 80 percent. I also led rollout of a new SIEM platform to reduce false positives and improved triage efficiency, while strengthening security compliance and audit preparation through regular vulnerability assessments.
