Hi! I'm John, a freshman studying Electrical & Computer Engineering at Berkeley. I build robots — ranked 2nd in the world — model and run simulations in Blender, and shoot photos at night.
Three of my favorite projects. The full list - 17 projects dating back to 2022 - can be found on the projects page.
7 DoF bi-manual robotics arms. Built for Robotics Center of Silicon Valley (YC S25); A custom rebuild of the open-source OpenArm — casings redesigned in CAD, wiring reworked, and the stock camera swapped out.
My robot for the DECODE season and my fourth and final FTC build. Took the Overall Inspire Award at the Chesapeake Championship, then a Division Inspire Award at the World Championship — 1st in the US, 2nd in the world.
A machine learning pipeline that segments and tracks tools in egocentric video of a tailor at work. It chains two foundation models: Grounding DINO, an open-vocabulary detector, localizes objects from the plain-English names a Gemini captioning stage produces, and SAM2 propagates each mask through the video, re-detecting every few seconds so new objects get picked up.
