An introduction to Domain-Driven Design (DDD) that focuses on the importance of communication between developers and domain experts.

The talk discusses how to effectively model business requirements using Laravel's Eloquent ORM while following domain-driven design principles. The speaker demonstrates how to create clean, maintainable code by properly encapsulating business logic, using domain-specific language, and avoiding leaky abstractions. Using an award management system as an example, he shows how to evolve from simple CRUD operations to more complex domain models while keeping the code aligned with business terminology and requirements.
