Do you have a resource on where to learn DDD? I feel like I never understood the concept well.
If you can work with python cosmic python (http://www.cosmicpython.com/book/preface.html) is a great resource
As already mentioned, the blue book by Evic Evans is a good reference, but it's a ittle dry. Vaughn Vernon has a book, "Implementing Domain-Driven Design" that is a little easier to get into.
Personally, I found that I only really grokked it when I worked on a project that used event-sourcing a few years back. When you don't have the crutch of just doing CRUD with a relational database, you're forced to think about business workflows - and that's really the key to properly understanding Domain-Driven Design.
Yeah for me the understanding really came when working in a federated GraphQL API. Each team had us own little slice of overall object graph, and overlap / duplication / confusing objects across the whole domain were a lot easier to see in that environment.
"Domain Driven Design" by Eric Evans, aka the blue book. It's very dense however and very object oriented, but concepts apply even if you dont work with object oriented languages, you might have to do more footwork to get from a domain model to services that adhere to the model.
"Head first Software Architecture" might be an easier on ramp and touches on simmiliar concepts.
