About Me

Background
and focus.

I'm a builder at heart. Over the past decade I've grown from software engineering into engineering leadership in the mobile world — shipping products people actually use and leading the teams that build them.

Today I work at Robinhood, and on the side I'm building Bolt's Adventures, a brain-training game that turns bite-sized challenges and personalized learning into an adventure.
