I'm a freshman at Harvard interested in EE, Stats, and Religion. I grew up in Hong Kong and went to Phillips Exeter.
I placed #1 on HN for open-source PCB design, built competitive undewater ROVs, and made games with 3+ million plays. I also read/wrote Latin and Attic Greek, composed atonal music, and captained HS varsity squash.
The world is changing incredibly fast. I'm currently thinking deeply about consumer and entertainment.
I designed open-source PCBs in KiCad for MUREX, Exeter's underwater robotics team, where I was an EE and then captain (2022–26). I built our power, networking and motion boards for the sake of vertical integration and fun.
Highly integrated electronics design and printed circuit boards (PCBs) for the MATE ROV Competition. Attempt the impossible.
The world's smallest and lowest-cost network switch: 5-port 100BASE-TX on a 4-layer board measuring 44.9 × 42.2 mm, with a $7 BOM. Advised by my friend Byran. It hit #1 on Hacker News and was covered by Tom's Hardware, TechSpot and ALL3DP.
Open-source dual-output, high-power module for 12V/5V/3.3V systems. Two TPS568230 bucks, LTC4352 ideal-diode protection with back-to-back MOSFETs, and INA226 power monitoring.
[Reference design] The world's first USB-modular, high-power-density ESC capable of sensorless FOC. It pairs an RP2040 with TI's DRV8316C motor driver and uses dual USB for power, hot-swapping and live programming. Rated at 40 V / 8 A peak.
A modular power-protection board for ROVs. An LM7481 ideal-diode hat plugs into a MOSFET power panel, and it's tested at 300 W (12 V @ 25 A) with jumper-selectable UVLO/OVLO.

Before high school I made games on Scratch as @xamuil2, writing the code, drawing the art and sometimes composing the music. I also ran a tutorial channel. Afterwards, I became a youth advisor and worked with the product team on development features and community design for two years.

My Unveiling (2025) is a five-piece album about language, memory and consciousness. I studied composition under Dr. Jon Sakata and placed 2nd in the 2026 Pittman Composition Competition.
As Chief Digital Editor, rebuilt the site and publishing pipeline for America's oldest continuously running prep school paper (React, Strapi, RDS, AWS). Migrated 10k+ articles; 85k+ page views a year.
Heu, crudele Catulle, perurens pectora nostra, basia non laedant, numquam iterum excrucier. Eripuisti mentem nostram ut nil nisi bellae senserim. Eripuisti, olim agilem celerem. “Formosa,” dicas, et cum cantat, sidera fulgent5 candidiora, homines rectius esse volunt. Tu Crudele Catulle! Perurere amore furens tam ut nostra otia frangam modo carminulis.
