Senior Product Security Architect

About me

Senior Product Security Architect with 15+ years of experience across software engineering, enterprise integration, solution architecture and cybersecurity. I specialise in helping product and engineering teams build and maintain secure, resilient and compliant products, combining hands-on technical experience with architecture, risk management and stakeholder engagement.

In my current role, I provide product security and security architecture expertise across a portfolio of products and solutions. My work includes security architecture reviews, product security assessments, architecture and threat modelling, vulnerability assessment and remediation, penetration-testing coordination, security risk management, secure development guidance and regulatory readiness.

My engineering, architecture and security background lets me bridge the gap between security requirements and practical technology implementation.
