About

All-rounder inspired by polymaths. I describe myself as a curious intellectual who also gets my hands dirty in front line execution. Diverse breadth of experiences across MNCs, government, startups and trade association, with direct experience in the macro (principles, vision, strategy), the micro (processes, operations), and everything in between. Core interests in science, technology and hardware applied to Climate Change Mitigation and Adaptation. Currently in a front-row seat of a scale up company.
