I am a vice president at Chef, a lecturer at UC Berkeley, and co-author of the Jolt Award winning Continuous Delivery, published in Martin Fowler’s Signature Series (Addison Wesley, 2010), and Lean Enterprise, in Eric Ries’ Lean series. I've worked as a software developer, product manager, consultant and trainer across a wide variety of domains and technologies. My focus is on helping organisations deliver valuable, high-quality software frequently and reliably through implementing effective engineering practices.
