I design and build rockets, the flight computers that fly in them, and the tools I need to make both. This is a record of what I've built so far.

Projects

High-power rocket · L1 & L2 certification
Zephyr
My 4-inch-diameter high-power rocket, built in two iterations as the platform for my Level 1 and Level 2 certification flights.
June 2026 — Now

Minimum-diameter rocket · Mach 1 attempt
Needlepoint
A minimum-diameter high-power rocket designed to reach Mach 1 on an H-class motor, carrying onboard flight avionics.
June 2026 — Now

Rocket avionics
Custom ESP32 Flight Computer
A custom avionics board that reads pressure, temperature, and acceleration, detects flight events like apogee, and fires the parachute deployment circuits.
June 2025 — Jan 2026

University rocketry club · SEB
Space Enterprise Berkeley
I'm on Space Enterprise Berkeley's carbon fiber composites team and help with liquid rocket engine assembly and testing.
Fall 2026 — Now

Fabrication process
PCB Photolithography at Home
I turned an MSLA resin 3D printer into a UV exposure unit so I could make my own circuit boards without sending them out to a manufacturer.
June 2025 — Now

Experimental research · structural dynamics
How 3D-Printed Infill Patterns Affect Vibration
I designed a vibration test rig and Python analysis pipeline to measure how four PLA infill patterns change a part's natural frequency, damping, and vibration transmission, then co-authored a 20-page paper on the results.
June — Aug 2025

Machine build · GRBL motion control
Custom CNC Machine
A CNC machine I designed and built from repurposed 3D-printer parts, with the motor-control side wired and configured by me: external stepper drivers on an Arduino CNC shield running GRBL. It cut acrylic for the projects that came after it.
Aug — Dec 2025

First rocket · high school team
Rocket Project v1
Our first rocket: almost entirely 3D printed, with avionics I designed from scratch. The goal was a stable flight to at least 400 feet on a high-school budget.

About
Hands-on since high school.
I'm a first-year Aerospace Engineering student at UC Berkeley with several years of hands-on experience in embedded systems, custom PCB design, and experimental rocketry. I'm most interested in autonomous aerospace systems and hardware development.
