This presentation uses live coding to show how to implement and implement a CQRS architecture using functional abstractions, pure functions and immutable data using Kotlin as language. CQRS concepts go very well together with functional programming principles of immutability and high level functions. Participants don't have to know Kotlin or functional programming but the knowledge can be beneficial. The session tries to capture the main architecture critical decision in implementing a cqrs application. We also believe that using a functional approach simplify the code and avoid some typical pitfalls in event store implementations. Of course it can bring to other problems so we discuss those as well.
