Tell about your experience implementing and using Domain Driven Design in projects.

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

In my experience implementing DDD in PHP projects, I:

• Divided code into layers: domain (entities, aggregates, repositories), application (services), infrastructure.
• Used the concept of aggregates to manage data integrity.
• Created clear boundaries of contexts (Bounded Contexts) to isolate different parts of the system.
• Actively collaborated with domain experts to clarify requirements and terminology.

Example: In an online store project, I identified the "Orders" context, where the Order entity managed order states, and the repository handled saving and loading orders from the database. This helped avoid mixing business logic with technical details and simplified maintenance.
