/ˈhæri ʃin/ · he/him · based in Shanghai 🇨🇳
IB student at Shanghai Pinghe, building toward physics & engineering. Core member of FRC 6941 IronPulse. I make small hardware, open-source tools, and video essays — things that work, explained plainly.
I'm a Grade 11 student at Shanghai Pinghe Bilingual School (Class of 2027), taking IB with HL Mathematics AA, Physics, and English B. I'm aiming for the Stanford / UC Berkeley track in physics, math, or engineering — and one day, work that ships, somewhere like Apple or DJI.
Most of what I do starts as a question and ends as something you can hold or run: an electrochemistry experiment, a seating-optimization model, a storage gadget that lights up the part you're looking for, or a small command-line tool. I also make literary & documentary videos — close readings, reflections, things worth slowing down for.

I make video on Bilibili and WeChat Channels, and longer essays on YouTube — literary BookTube (Of Mice and Men, A Raisin in the Sun) and short documentaries, including the Empire in Decay: Echoes of the Empire series from our FRC trip to Istanbul. The aim is always the same: down-to-earth, human, and worth the runtime.
