Moving Fast (without crashing) - Javascript NZ

At Pushpay we deploy to production up to a dozen times a day. This talk will explain how we can do that consistently, and how we can maintain a high quality codebase with minimal technical debt. We will discuss the culture that enables this, and that helps us easily recover when things do go wrong.
