Computer Science and Mathematics at NUS. I build useful products, lead ambitious student teams, and care about the details that make technology feel human.

About

Code, product, and people.

I enjoy taking ideas from a rough problem to a working product - from language learning and AI commerce to tools for fellow NUS students.

Outside the code, I serve as President of the NUS Students' Computing Club, working with student leaders to support a community of about 6,500 students.
