01. About

I'm a software engineer based in Canada, with a B.Sc. in Computer Science from the University of British Columbia (GPA: 87.7).

I've been recognized with the Faculty of Science International Student Award and the Deputy Vice-Chancellor Scholarship for academic excellence.

When I'm not writing code, you'll find me playing chess, soccer, or diving deep into how systems work under the hood.
