What I'm looking for

I seek a senior security role where I can lead cross-functional teams, drive ISMS and cloud security programs, mentor staff, and strengthen enterprise resilience while ensuring regulatory compliance and measurable risk reduction.

I am an IT security leader with over 20 years in the IT services industry, focused on protecting hybrid environments across cloud, on-premises, and multi-datacentre infrastructures. I have led cross-functional teams, driven regulatory compliance (ISO 27001, PDPA, PCI DSS), and implemented enterprise security controls including SIEM, EDR, MFA/IAM, network encryption, and cloud-native protections.

I deliver pragmatic risk mitigation and operational security—leading data center migrations, ISMS implementation, penetration testing and vulnerability management, and deployment of controls such as WAF, IDS/IPS, VPN, and cloud monitoring. I emphasize coaching and team growth, continuous improvement, and embedding a culture of resilience, trust, and security awareness across organizations.
