Profile README

Hi there 👋

I'm currently building perception systems for robotic applications at @perceptual-ai.

Previously, I spent my open-source time working on Emmy, a computer algebra system in Clojure that's designed for explorations in symbolic math, classical mechanics and differential geometry.
