    Using Ktor from JetBrains, you can easily build a server backend using a composable DSL and Kotlin features like coroutines. Ktor runs in standard server environments, like Google's App Engine, which will host and scale your backend automatically.

    In this talk we build an in app purchase verification backend for your app from scratch, using Ktor. You'll see how Ktor's composable DSL makes server development fast and easy, and understand how you can quickly build a REST API and admin interface.
