You've probably heard or even practice Hexagonal Architecture, Clean architecture, Onion layers... you name it.
Perhaps one of the most discussed software architectural pattern.
Strangely, its implementations are subject to a wide range of interpretations.
But, undoubtedly, its major advantage, whenever you implement, is ... Testability !!!!
Somehow, it has been forgotten.

So let's dive into practical, real life examples and tactics.

Quick Live coding and samples from the trenches included.
TDD all the way. C# Net Core or Kotlin.

This conference comes with a workshop where you will mob on a concrete example.
