If you have ever built a web application, chances are that you have also had to deal with "the back office" - the chores and one-off tasks required to operate your software in production. Workflows that aren't user-facing, like creating promo codes, moderating content, or running reports, are often a janky combination of admin scripts and spreadsheets. Retool helps developers quickly and easily solve these problems with software instead. In this session, we'll show how to build a back office interface for a Ruby on Rails application using Postgres and several common API services, so you can keep your focus on the business in the front, and let Retool help throw the party in the back (office).
