I’m an executive cybersecurity leader, security architect, and post-quantum cryptography researcher with 31 years of IT experience and 22 years focused on information security for Tier-1 financial institutions. Over the years, I’ve designed and led Zero Trust security architectures, built enterprise security programs, and provided board-level cyber risk and governance guidance across regions including the US, EU, and the Caribbean. My work combines practical security engineering with rigorous compliance and risk management—spanning ISO 27001, NIST CSF/800-53/207, DORA, PCI DSS, GDPR, MiCA, and VARA. I also drive modern cryptographic transitions by implementing post-quantum hybrid approaches (e.g., X25519 with ML-KEM-768 and migration paths with ML-DSA) and contributing to standards, including IETF policy-bound authorization and capability token frameworks.…I’m an executive cybersecurity leader, security architect, and post-quantum cryptography researcher with 31 years of IT experience and 22 years focused on information security for Tier-1 financial institutions.
