Easy.Platform provides a complete foundation for enterprise application development:

• Clean Architecture: Four-layer architecture (Domain, Application, Infrastructure, Presentation) ensuring separation of concerns and testability
• CQRS Pattern: Command Query Responsibility Segregation with fluent validation and event-driven side effects
• Event-Driven Architecture: Domain events and RabbitMQ message bus for cross-service communication
• Multi-Database Support: MongoDB, SQL Server, PostgreSQL with unified repository patterns
• Angular Integration: PlatformVmStore state management, base components, and reactive forms

The framework is battle-tested in production enterprise applications and provides patterns for common challenges like background jobs, data migrations, authorization, and multi-tenancy.
