Tell me, are you familiar with the Domain Driven Design (DDD) methodology? If yes, share examples of its application in your projects.

Yes, I am familiar with the Domain Driven Design (DDD) methodology. It helps structure complex projects by focusing on the business domain and its logic.

In one of my projects, I applied DDD to divide the system into several bounded contexts, each responsible for its own business area. This allowed teams to work independently and avoid conflicts.

The main elements I used:

• Entities — objects with a unique identity.
• Value Objects — objects without identity, defined by their attributes.
• Aggregates — groups of related objects with a root, through which access is provided.
• Repositories — abstractions for data access.

For example, in a project managing orders, I defined an aggregate "Order" that encapsulated logic for adding products, changing status, and calculating cost, which simplified maintenance and code development.
