As mobile developers, we often see the backend world as something magical that "does things". But what if I tell you that you can easily build a backend even if mobile is your thing? With this talk, I want to show how it is possible to bring your mobile knowledge (and shift it a little bit) to build a backend with Kotlin and Ktor. I will show how to structure the project, set up Dependency Injection, connect to a database and test everything to have a working backend ready to be deployed.
