About

Enterprise-focused cybersecurity professional with over 10+ years of experience shaping security architecture and risk strategy across cloud and infrastructure environments. My work centers on designing scalable, risk-driven security frameworks that align protection capabilities with business and regulatory objectives. I bring deep expertise in vulnerability governance, PKI/CA infrastructure, and cloud security architecture, translating complex technical risks into structured remediation roadmaps and enterprise-level control improvements aligned with ISO 27001 and PCI-DSS. Beyond technical execution, I lead and collaborate with cross-functional stakeholders to define security baselines, review system and cloud designs, and guide risk-based decision-making that balances compliance, operational realities, and long-term strategic direction. With an offensive security foundation (OSCP/OSCP+), I incorporate attacker-informed insight into architectural design and governance discussions. I am particularly interested in advancing enterprise security through strategic architecture, automation-driven security optimization, and continuous risk visibility at scale.
