Ya, it scales very well to bigger project in fact.

The thing is, people do struggle to understand how to implement it and what it's all really about.

I recommend Vaughn Vernon - Implementing Domain-Driven Design for a good walkthrough of it in C#.

And I also recommend you look at my small demo example, which is in Clojure, but also walks you through what DDD is at a high level which should help you quickly grasp it (even if you don't know Clojure) in a literate programming form: https://github.com/didibus/clj-ddd-example
