About

I’m a product design engineer at Amazon in San Francisco, working on consumer hardware — ambient AI wearables and Ring and Blink security cameras and doorbells. I take products from concept through to mass production: the mechanical architecture, integrating RF, optics, PCBA, thermal and battery into an industrial design, and then the unglamorous part that decides whether a product actually ships — tolerance stacks, DFM, and EVT and DVT builds on the floor at contract manufacturers in Asia.

Before this I spent two years designing drug delivery devices in India, and started a 3D printing company that served dental clinics. Those projects are documented in full in the work section — they are where I learned to design mechanisms that have to work the first time.

Enthusiastic about design, cars, martial arts and chess.
