About

I’m a computer vision engineer in the San Francisco Bay Area. I’m currently at Zipline, where I work on perception algorithms to enable safe and precise instant deliveries. Previously, I worked at Iron Ox and Matterport, where I focused on 3d scanning of plants and buildings, respectively. Before that, I briefly worked at Amazon Lab126, and received my B.S. and M.S. at UC Berkeley, where I was a member of the Vision and Image Processing Lab.

Selected Work Experience

Zipline: Perception Engineer (2023 - Present)

Iron Ox: Staff Computer Vision Engineer (2020 - 2023)

• Built multi-camera imaging stations to capture thousands of plants in 2d and 3d
• Used 3d plant scans in conjunction with environmental sensors to predict future plant growth for yield and sales forecasting
