Confessions of a Backend Developer
summary
Argues that MVC/ADR leave the model as an ad hoc mess and shows how Clean Architecture (hexagonal/onion) keeps the domain core independent so business logic tests run without framework or database. Demonstrates DDD primitives: user ID value object, money and entity patterns, repositories that swap storage, application services for translation, domain services for cross-entity flows. Shows PHP techniques that enforce immutability and types—protected clone, disabling magic setters, hand-rolled enums and a type-safe callable wrapper—and claims these make the design portable and verifiable.
