ABOUT
More About Me
I've always been the person my family calls to fix a computer or explain how an app works. I'm a 15-year-old from Hong Kong who loves to code. But the more I helped my grandparents, the more I realized the problem wasn't them—it was that no one ever taught them the "language" of the internet. They're smart people, they just never learned what a "cookie" or a "cache" is.
That frustration I saw on their faces is what motivated me to build Lumin. It started as a small project to help them but turned into something much bigger. I'm using what I know to hopefully make the digital world a less confusing and more welcoming place for everyone, not just my generation.
SUPPORT
How we work and
how you can support us
Lumin is—and always will be—free to use. But if you’d like to help us keep the lights on and make the tool even better, you can support us in a few meaningful ways:
Buy Me a Coffee
I’m still a student, and every coffee (or bubble tea!) helps fuel those late-night coding sessions and lets me spend more time improving Lumin.
