Versal is an edtech platform. We have a full Scala backend for RESTful API and a JavaScript frontend. In this talk we outline the whole trajectory from nothing to a working company where Scala does the heavy lifting. We describe the event sourcing architecture, and Jellyfish, an open-source project which decouples the web framework from logic. We show how abstraction allows us to not get married to any particular implementation, replacing them by more performant ones as needed. We also describe how our community relationships -- running a Scala for Startups meetup -- helps us stay on top of the best practices for Scala engineering.
