I love building intelligent systems of people and computers, and working with multidisciplinary teams that make those systems possible. I draw from broad experience spanning entrepreneurship, product management, machine learning, data visualization, software engineering, human-computer interaction, experiment design, and economics.


Parsnip Parsnip

2020—present Co-founder and CEO
Parsnip (“Duolingo for cooking”) applies the same feeling of “leveling up” in a video game to the real-life skill of cooking, so that anyone in the world can conveniently cook any cuisine at home. Our long term goal is to create a personalized AI companion for the home kitchen that teaches cooking and helps you figure out what’s for dinner.

Parsnip gained over 35k organic downloads, reached 4.9⭐ on the App Store, and was featured by Apple. Our users loved us and we probably reached product-market fit. We raised $450k from angel investors including the co-founders of Duolingo and a James Beard laureate, and learned a ton from making many mistakes.
