OOP / DDD Architecture Expert

Need well-architected PHP code? I apply OOP, Domain-Driven Design, and SOLID principles to build Laravel applications that are easy to maintain, test, and extend — even years after initial development.

Services & Capabilities
🏛️
Domain-Driven Design
DDD in Laravel — Domains, Aggregates, Value Objects, Domain Events, and Bounded Contexts for complex business logic.
📦
DTO Pattern
Data Transfer Objects for clean data flow between layers — typed, validated, and explicit contracts between application components.
🗃️
Repository Pattern
Database abstraction with repositories — swap storage backends without touching business logic.
🔧
Service Layer
Application service layer separating HTTP concerns from business logic — testable, reusable, and framework-agnostic.
📐
SOLID Principles
Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, Dependency Inversion — applied pragmatically.
🧪
Testable Architecture
Code structured for unit and integration testing — dependency injection, interfaces, and no hidden global state.

FAQ
Should every Laravel project use DDD? +
No. DDD adds complexity justified by complex business domains. For simple CRUD apps, standard MVC is fine. I apply the right level of architecture for the problem.
What is a DTO and why use it? +
Data Transfer Object — a typed container for data passing between layers. Prevents passing raw arrays, makes contracts explicit, and improves IDE support.
Do you follow all SOLID principles strictly? +
I apply SOLID pragmatically — the goal is maintainable, readable code, not dogmatic rule-following. Some principles apply more than others depending on context.
Can you refactor spaghetti PHP code to clean OOP? +
Yes. I audit existing codebases, identify architectural problems, and incrementally refactor toward clean OOP without breaking functionality.
Do you write unit tests with the clean architecture? +
Yes. Clean architecture with dependency injection makes unit testing straightforward — mock dependencies, test logic in isolation.
