uc berkeley · class of 2029

I'm a CS and Linguistics double major at Berkeley, focused on NLP and ML. I've worked on SightLine, a ML Day-Recap App using Meta Ray-Ban Glasses, website development for Xaitsnoo, a critically endangered language, and contributed to Japanese–English translation research through Berkeley's URAP. This semester, I joined Geopogo as an AI training researcher and started building an autonomous maze-solving robot in Micromouse.

I like building projects, learning languages, and getting to know new people. Don't hesitate to reach out if you want to talk about anything CS or Linguistics related, or, anything, really.

Signage

Real-time ASL-to-English translator that turns webcam or phone video into live English subtitles. 2nd Prize, AI Assistants Track ($4,500 AWS credits) at The Executable World Hackathon, built on a 5-person team. Trained a TensorFlow.js recognizer on MediaPipe Holistic pose keypoints covering 3,272 ASL signs (70% top-1, 84% top-5), with the Claude API composing fluent English from the recognized sign sequences.

Sketches

DPD (Digital Painting Decal)

I joined the Digital Painting Decal on campus during my freshman spring, and it was one of the best experiences I ever had. Not only did I meet my current girlfriend there, but I also had the chance to make this as my final project! I had a lot of fun learning how to draw.

Mafu Chrysalis

This was my first rendition of my D&D OC, Mafu (Along with my other party members, Teotl and Nox), who later became the inspiration for the game Debate Club from Hell. I was pretty proud of this.

Language Learning

JLPT N2

Passed the JLPT N2 (Japanese Language Proficiency Test), the second-highest level. Currently working toward N1!

Writing

Writing Portfolio

I did a lot of creative writing! Here are some excerpts, if you're interested. Depending on how this CS thing works out, I might have to pivot... /halfjoking
