About me
Building at the intersection of craft & code
I'm a Year 3 Computer Science student at the National University of Singapore, graduating December 2026. I love building products that people actually use, and I've been fascinated by the power of AI tools to reshape the way we build — automating workflows and accelerating what's possible, even for developers.
I'm currently interning at Stripe as a Software Engineer under the Cards team. Previously, I interned at PayPal under the Global Compliance team. Outside of work and school, I compete in hackathons and am currently helping organize the NUS SoC TIPs Program 2026 — and somewhere in between, I aspire to build my own startup, a tool that would benefit the lives of many people, including myself.
Looking forward, I am open to full-time developer opportunities in Singapore or the United States upon graduation.
