She has shipped production code in 8 different coding languages to millions of users. Ask her about her thoughts on being a startup person at heart finding her footing in a large company, her love for mentoring, the welcome challenges of onboarding new engineers, and how great software engineers do so much more than write code! She is the mom of two amazing little kids who drive her to want to do some good in the world.
