Learn how to transform a monolithic application into a well-structured modular system with clean public APIs. This guide covers essential concepts of modularity, coupling, and architecture testing to help you build maintainable applications. From basic principles to practical implementation, discover how to create explicit contracts and move from direct data access to professional public APIs.
