SAMWISE CubeSat

SAMWISE is a 2U CubeSat designed from scratch by the Stanford Student Space Initiative (SSI), targeting launch in July 2026 aboard a SpaceX Transporter mission from Vandenberg Space Force Base. I've worked on SAMWISE through many iterations for two years. As satellite structures mechanical team lead, I'm responsible for leading fabrication and integration of the satellite structure, test engineering of components, and collaboration with other teams(i.e. avionics, software, etc.) for launch readiness.

Frontier TrailCam

Remotely accessible, Programmable, Arduino-based, Timelapse Camera Stations, with three units having been deployed to monitor invasive plants at a nearby nature preserve. Built on the ESP32-CAM with two startup modes: configuration over a built-in web server (live stream, camera tuning, and capture schedule controls) or autonomous photo capture using saved settings. Between captures, the system enters deep sleep while a DS3231 RTC tracks wake time for low power operation. Images save to a FAT32 microSD card, and the unit runs on dual 18650 batteries for field deployment. Cases are custom 3D printed and designed, and this used self-soldered ciruitry and arduino code.

Sprout

Autonomous robotic microfarm: Camera and water line moveson a custom 2-axis gantry. Using the camera soil moisture, pressure, and air-quality sensing; a locally running AI model on a NVIDIA Jetson Nano makes per-plant watering decisions. I led the mechanical engineering, riveting the metal frame, building a functional 2-axis gantry system, 3D printing parts, creating a water line system, all in 24 hours. Project was a winner on the NVIDIA Edge AI Track at TreeHacks 2026, winning an Asus GX10 AI Supercomputer, NVIDIA Jetson Nano, $800 in AI credits, and a visit to NVIDIA's headquarters.

Studio Stand & Stylus

Stand and stylus designed from scratch and fabricated from 6061 T6 Aluminum. The Stand has a ball detent for easy click in-click out three positionheight adjustment. The stylus has a knurled grip and rubber tip. Fabrication includes turning, milling, knurling, external threading, & more. Used drill bits, endmills, angle blocks, mill collet blocks, radius cutter, external threading tool, and more.

Toolbox & Hammer

Hammerhead was sandcasted, then holes & threading for the endcaps and hammer were added on the mill. Hammer endcaps, shaft, and threading were turned and added on the lathe. Everything was finished with sandpaper and polishing. Toolbox is bent front sheet metal, and each side is fastered differently. One is riveted, one uses PEM nuts, one is oxy acetylene welded, and one is spot welded.
