Executive Summary

Technical Architect and former CTO with 15+ years leading engineering teams and partnering with business leaders across Asia. I specialize in modernizing legacy ecosystems, designing cloud‑native, event‑driven architectures, and aligning technology decisions with commercial priorities, regulatory constraints, and operational realities.

I operate at the intersection of business strategy and technical execution—translating complex requirements into scalable systems, shaping product direction, and enabling organizations to deliver faster with lower risk. Known for cross‑functional influence, I help business, product, and engineering teams converge on clear decisions, predictable delivery, and measurable outcomes.
