About

I am an EEE undergraduate at NTU who likes building things — from registers and state machines to webpages and services that you can actually use.

I care about systems that survive contact with the real world — firmware that boots, pipelines that converge, and interfaces that stay out of your way.

Building reliable systems across hardware and software.
