Scaling Ruby Development for Healthcare

by Kevin Shekleton and Nathan Beyer


At Cerner, we build healthcare software in a highly regulated and heterogeneous environment. Today, Ruby is a core component of our architecture, powering healthcare applications and services written by over two hundred developers. Our current state is the result of a three year evolution to grow adoption of Ruby that still continues to this day.

In this talk, will walk you through the steps we took to demonstrate a peaceful coexistence with our existing technology stack that ultimately lead to leadership and developer buy-in. We will also discuss how we maintained adherence to a structured development process that requires documentation and testing evidence with minimal developer friction. And finally, we will cover how we grew our developer community to one of hundreds of happy and productive Ruby developers.
