Josh W Lewis is a multi-discipline engineer who has been building web applications and development tooling for nearly a decade. Lately, he's been building new workflows for developers on GitHub, delivering Heroku Pipelines and Review Apps and leading the development of Heroku CI as part of a small, high-performance team.

Abstract

Continuous Integration and continuous delivery are the key to code quality, product agility, and engineering velocity. In this session, you’ll learn how your team can use GitHub, Heroku Pipelines, and Heroku CI to make continuous delivery simple and flexible. The Git-based methodology provides for a pipeline through which code begins as a fully executable pull request, goes through automated unit and integration tests, is automatically merged to test and staging apps, and is then deployed to production with a single click. Some customers are able to deploy features and fixes up to 500+ times a week, with very few rollbacks from production. Developers with an intermediate level of experience will benefit the most from this workshop.
