About

I spent seven years at Shopify designing shipping and fulfillment software, starting as an intern and leaving as a senior designer.

I enjoyed working on larger problems that spanned multiple teams—taking them from initial pitch through to execution.

I'm currently based in Tokyo, going to Japanese language school, and building my own tools on the side. I'm looking for a product design role at an English-friendly company in Japan.
