About

A bit about how I work

I'm a full-stack engineer passionate about building products from the ground up. I enjoy personally crafting every detail, from the underlying data models and RLS policies to the very last hover animation on the front-end. My practical experience includes e-commerce system development and front-end development for Taiwan's largest job search platform. I also hold a Master's degree in Interactive Media from the University of Technology Sydney (UTS).

For me, AI is not a passing fad, but a powerful assistant in daily development. I use it to accelerate output and validate results, but I always retain the final technical decision-making authority. This website is the best testament to this: it's not just a static resume, but a real application with a complete built-in CMS and AI assistant.
