Architecture Patterns

Master proven backend architecture patterns including Clean Architecture, Hexagonal Architecture, and Domain-Driven Design to build maintainable, testable, and scalable systems.

When to Use This Skill

• Designing new backend systems from scratch
• Refactoring monolithic applications for better maintainability
• Establishing architecture standards for your team
• Migrating from tightly coupled to loosely coupled architectures
• Implementing domain-driven design principles
• Creating testable and mockable codebases
• Planning microservices decomposition
