Stephen Nelson-Smith (SNS) is an internationally respected consultant, mentor, and coach to organizations seeking to succeed in their ongoing digital transformations. One of the founders of the Devops movement, he is a specialist in infrastructure automation and continuous delivery, with a particular emphasis on Chef. As an O’Reilly author, he is credited with inventing Test-driven Infrastructure, a discipline bringing the benefits of test automation and requirements-driven development to the coded enterprise. A frequent keynote speaker, he has presented at multidisciplinary conferences including Velocity, where he has been on the programme committee, QCon, Web Summit, Devopsdays and Kings of Code. His client list is wide-ranging, including, for example, RBS, Capital One, BBC, Capita, Sony, SAP, Thoughtworks, Elsevier, and Easyjet. SNS has a deep technical background in UNIX systems, Enterprise Hosting, and public and private cloud, and has architected and run web scale infrastructures across multiple technologies and architectures, encompassing traditional on-premise three-tier Java/Oracle stacks, through AWS-based Python/Scala/Clojure microservices, and Node/Erlang web/api platforms. A serial entrepreneur, he was founding CTO of disruptive financial Cloud Broker, Strategic Blue, a Techstars accelerated company, and co-founder of ground-breaking Devops consultancy Atalanta Systems, meaning he understands the challenges and needs of organizations from the emergent to the established. Stephen blends ideas from acceptance and commitment therapy, non-violent communication, mindfulness, clean language/learning and distributed cognition to shape an approach to digital and organizational health that goes beyond technology and agile frameworks.
