Singapore, Singapore
With extensive leadership experience in Information and Communication Technology, I specialise in building secure, resilient, and scalable technology foundations for modern financial services. My expertise spans IT Security, Platform Engineering, Cloud Infrastructure, Site Reliability Engineering (SRE), DevSecOps, and AI-native platform engineering, enabling organisations to operate highly automated, compliant, and innovation-driven technology ecosystems. I combine strategic leadership with hands-on engineering depth, working across business, technology, risk, and audit stakeholders to turn complex challenges into scalable and secure platform solutions. My focus is on aligning security architecture, platform strategy, operational resilience, and engineering practices to support sustainable digital growth in highly regulated environments. I am particularly interested in shaping the next generation of banking technology through Agentic AI infrastructure and AI-native platforms, building the guardrails, operating models, and engineering foundations required for safe, governed, and production-ready AI adoption at scale.
