Do you have experience applying Domain-Driven Design (DDD) in your projects?

Domain-Driven Design (DDD) is an approach to software development that focuses on a deep understanding of the subject area and building a model that reflects business logic.

In projects using DDD, it is common to:

• Identify core domain entities and aggregates.
• Use language constructs close to the subject area (Ubiquitous Language).
• Divide the code into layers: domain, infrastructure, application.

An example of application in Python is creating classes that reflect business logic without mixing with technical details:

class Order:
    def __init__(self, items):
        self.items = items

    def total_price(self):
        return sum(item.price for item in self.items)

Thus, DDD helps make the code more understandable and maintainable, especially in complex business scenarios.
