01 — About

About

I am an undergraduate at UC Berkeley studying Electrical Engineering & Computer Science. Go Bears!

My interests lie in machine learning and robotics. As of Spring 2026, I joined AUTOLab, where I work on medical imaging technology for sutures and benchmark autonomous surgical debridement pipelines.

Welcome to my little corner of the internet! 🫶

02 — Work

Selected projects

A few things I've built. Each one taught me something I still use.

Berkeley AUTOLab

Spring 2026 — present

I work on medical imaging technology for sutures and benchmark autonomous surgical debridement pipelines — measuring how reliably a robot can identify and remove damaged tissue, and where those pipelines still break down.

GamesMan — GamesCrafters Research Group

Fall 2025

At UC Berkeley's GamesCrafters Research Group, I contribute to GamesMan, a system for solving and playing two-person abstract strategy games perfectly. I implemented and fully solved game variants — most notably 9 versions of Hexapawn — storing solutions in a high-performance database. The team improves system efficiency with game-specific optimizations, including hash functions, while developing intuitive GUIs and new variants for interactive learning and strategy analysis. The work sits at the intersection of algorithmic game theory, software engineering, and educational tools.

Implemented and fully solved 9 variants of Hexapawn

  • Algorithmic game theory
  • Solvers
  • Databases

Classify

Fall 2025

A handwritten-digit classifier written in RISC-V assembly. Matrix multiplication, ReLU and argmax are implemented from scratch, so the whole neural network runs on hand-managed memory — a lesson in how much the abstractions above actually cost.

  • RISC-V
  • Assembly
  • Neural networks

Voice Recognition

November 2024

A speaker classification system built on SVD and PCA for dimensionality reduction, projecting recorded audio into a lower-dimensional space where the classes separate cleanly.

85%+ classification accuracy

  • SVD
  • PCA
  • Signal processing

Ngordnet

Spring 2025

A Java backend for exploring historical word frequency in the Google NGrams dataset. I implemented the TimeSeries and NGramMap classes that make the queries efficient, plus the plotting layer that turns them into readable graphs.

  • Java
  • Data structures
  • Visualization

Scheme Interpreter

November 2024

A Scheme interpreter in Python with environment frames, symbol lookup and user-defined procedures, using the trampoline technique for tail-call optimization so deep recursion doesn't blow the stack.

  • Python
  • Interpreters
  • Recursion

Also built

  • Percolation

    Spring 2025

    Monte Carlo simulation estimating percolation thresholds in a grid using weighted quick-union, with a visualizer for debugging.

  • Audio Positioning System

    October 2024

    Microphone localization from cross-correlation and least-squares estimation of time-of-arrival differences.

  • Ants v. SomeBees

    October 2024

    A turn-based tower defense game for CS 61A, built around an object-oriented model of ant placement and bee behavior.

  • Shazam Audio Fingerprinting

    September 2024

    Spectrogram-based song identification that matches a brief recorded clip against a fingerprint database.

  • Robocode Tournament

    2023

    Java robot programming with reinforcement learning to tune combat strategy over repeated matches.

  • Picture Lab

    2023

    Edge detection and pixel-level image processing algorithms written from scratch.

  • Pacman AI

    September 2021

    Pathfinding and search algorithms implemented for a UC Berkeley outreach project.

  • PigLatin Translator

    October 2022

    A utility that converts an entire book's text to Pig Latin, line by line.

03 — Engineering

Engineering

Before EECS, I spent high school in robotics and aerospace — competition teams, spacecraft design, propulsion testing, and a lot of things built to see whether they'd hold.

  • VEX Robotics

    2022 — 2023

    Served as team president in 2023, restructuring the club into separate building and educational sessions. The team earned the Judge's Award at the August 2023 regional competition and qualified for both the state championship and the CREATE US Robotics competition.

  • Mission to Mars Capstone

    April 2023

    Led a team of seven through a full Mars mission design — launch mechanics, planetary research, crew health protocols and a return trajectory built on Hohmann transfers and orbital mechanics.

  • Rocket Propulsion Analysis

    April 2023

    Measured impulse data from Estes A8-3, B6-4 and C6-5 motors using force sensors and test equipment, then analyzed how impulse affected rocket performance.

  • Mousetrap Car

04 — Principles

Principles

The handful of ideas I keep coming back to.

  1. Family

    I love my family and am super thankful for the life I am given. My family, both biological and by faith, mean the world to me.

  2. Discipline

    As the Navy says, pain is weakness leaving the body.

  3. Ship, then refine

    A working thing in someone's hands teaches more in a week than a spec teaches in a month. Iterate in public.

  4. Details compound

    One careful decision doesn't matter. Fifty of them are the difference between work that runs and work people can build on.

Away from the keyboard

I am an avid runner, triathlete, and reader.

Man reading should be man intensely alive. The book should be a ball of light in one's hand.

Ezra Pound
  • Running

    I ran my first half marathon in 2019 and have been pushing my capabilities ever since.

  • Triathlon

    I race with UC Berkeley's Competitive Triathlon team.

  • On the road

    The team has taken me to Santa Barbara, Davis, Cal Poly, and Florida to compete.

  • Hiking

    Trails and elevation, whenever I can get to them.

  • Reading

    I've always loved literature — Dostoevsky, Kafka and Hemingway most of all.

  • The list

    I am working toward 3/4 of the Modern Library's Top 100. Most recently finished #74, A Farewell to Arms.

05 — Contact

Get in touch

I am always glad to talk about research, machine learning and robotics, or new opportunities. The fastest way to reach me is email.

06 — Beauty

Beauty is the essence of Truth

Here are some things I have found beautiful of late.

  • A sunset at the end of a Berkeley street, light flaring down the road
    Sun going down over Berkeley
  • Florence at dusk seen from Piazzale Michelangelo, the Duomo on the skyline
    Florence, from the top of the hill
  • The interior of a church in Greece, candles burning beneath frescoed arches
    Candlelight (Church in Greece)
  • A bowl of tagliatelle with ragù, parmesan and a single basil leaf
    Tagliatelle worth the wait
