About me
I joined HKTVmall right after graduating from HKUST. Since then I've worked across the full stack — from Java Spring Boot microservices and SAP Hybris e-commerce to React and Next.js frontends serving millions of users.
I enjoy solving complex problems at scale, mentoring teammates, and building tools that genuinely improve people's workflows.
