Building payment infrastructure across Southeast Asia. Full-stack engineer with expertise in distributed systems, fintech, and building products from zero to one.

About

I'm a software engineer based in Hong Kong, currently working as a Founding Engineer at Hero Plus Group, where I architect and build payment infrastructure serving merchants across Southeast Asia.

My work spans the full stack — from designing PCI-compliant multi-gateway payment systems handling transactions across Thailand, Hong Kong, Malaysia, and Singapore, to building React frontends and managing AWS infrastructure.

Before Hero Plus, I worked as a Research Assistant at the University of Hong Kong, developing AR therapeutic games for stroke rehabilitation using computer vision and Unity. I also co-founded Solvfit, a skill-based talent matching platform.

I studied Computer Science at HKU, where I built a foundation in distributed systems, machine learning, and software architecture. Outside of work, I'm interested in fintech, developer tools, and building products that solve real problems.
