About

I am a software engineer who enjoys building delightful and performant web apps. I love learning new technologies and solving real problems with simple, thoughtful design.

With a strong foundation in competitive programming (Top 0.5% on LeetCode) and experience across the full stack, from building Redis in C++ to developing AI-powered web applications, I bring both systems-level understanding and modern web development expertise.

Pursuing my Bachelor of Computing at NUS as a Merit Scholar, I'm open to web development freelance work and seeking Summer 2026 SWE internship opportunities where I can contribute to impactful projects and continue growing as an engineer.
