I am an engineering leader and software engineer with over two decades of experience building scalable products, high-throughput platforms, and open-source software. Currently, I lead a distributed engineering team at Grab, where we build and scale payment infrastructure that powers driver payouts, fee management, MDR computation, and transaction processing across Southeast Asia. My focus is on designing reliable systems that operate at scale while enabling businesses to move money efficiently and securely. Before Grab, I was Head of Engineering at Tech in Asia, where I led the engineering organization and oversaw the platform’s technology strategy. In addition to managing the team, I was responsible for scaling Tech in Asia’s WordPress-powered publishing platform and developing custom solutions to support its growth across media, events, and jobs. Beyond my professional work, I have been an active contributor to the WordPress ecosystem since 2003, shortly after WordPress was forked from b2. I maintain multiple open-source projects and have published 21 plugins in the WordPress Plugin Repository, including widely adopted plugins such as WP-PageNavi, WP-Polls, WP-DBManager, WP-Sweep, WP-PostViews, and WP-PostRatings. I am a strong advocate for open source and believe in building software that benefits the broader community. Most of my projects are publicly available on GitHub and continue to be used by developers and websites worldwide.
