What I'm looking for

I’m looking to continue in senior vulnerability management and cyber risk roles—building resilience, improving prioritisation frameworks, and turning complex threat and vulnerability data into clear guidance for executives and engineering teams.

I’m a Senior Security Specialist in Vulnerability Management, with nearly five years at ASML progressing from Security Business Analyst to Senior Security Specialist. I bring deep expertise in strategic risk mitigation, ransomware resilience assessment, and enterprise-scale vulnerability management, guided by the NIST Cybersecurity Framework.

My work blends hands-on technical analysis with clear leadership communication. I build and operate vulnerability tooling such as a custom ServiceNow Vulnerability Response risk calculator, run exposure classification for enterprise asset prioritisation, and own Microsoft Defender for Endpoint through structured assessment across operational domains.

I also translate complex vulnerability intelligence into decision-ready guidance—authoring priority patch and risk communications for critical zero-days and producing executive-level reporting for risk-based decisions. I’m motivated by improving resilience, strengthening security processes, and helping teams act faster and smarter on real-world risk.
