I’m a mechanical engineer. I like building things you can hold.

Work

#01

ode. — Audiobook Player

I built a handheld audiobook player so I could listen without my phone. I soldered the electronics together and fitted them into a 3D-printed enclosure. I’m calling it ode. for now.

Tabletop Factory Model

A ten-foot working miniature of Corning's Harrodsburg glass plant, built with a small team during my Apple internship so stakeholders and press could understand the process without walking the factory floor.

Live Optical Alignment and Automated Lens Testing

I built a test rig and Python interface to speed up optical alignment and lens testing for a new microscope.

Toy Car

I designed a 1920s-style toy car for a manufacturing class, cast the body, and machined a mold for the wheels.

About

I study mechanical engineering at Columbia University and minor in computer science.

I worked on high-volume hardware as a Manufacturing Design Engineering intern at Apple. In summer 2026, I worked on ride development at Walt Disney Imagineering.

When I'm not on a factory floor or in the Creative Machines Lab, I'm usually embroidering, binding a book, or checking on whatever the 3D printer is up to that week.

Ride Development Engineering Intern

Walt Disney Imagineering

Developed ride systems for Avengers: Infinity Defense, an upcoming Avengers Campus attraction.

May 2025 — May 2026

Manufacturing Design Engineering Intern

Apple

Drove $2.8M+ in savings across DFM, tooling, materials, and assembly — including raising one assembly from 65% to 99.7% yield. Also built a tabletop model of a partner factory with a small team, later seen on CNBC.
