Currently working for Meta's Reality Labs, building the next generation of avatar editors. Before, I have worked for AWS's machine learning org, and Amazon Retail.

In my spare time I'm part of the team that organises Electromagnetic Field festival and you can find me at traveling around the world on off-years.
