If you’ve ever worked on an application where changing one database, framework, or external service unexpectedly breaks something elsewhere, this book tackles that problem directly. It shows how to keep business logic separate from the technologies surrounding it, using ports, adapters, and clear application boundaries.

The book takes a practical approach, following an application called WriteFlow as it evolves from good architectural intentions into a genuinely maintainable system. Along the way, it explores domain modeling, use cases and commands, repositories, data mapping, dependency inversion, and bringing all the pieces together in a running application.

Although the principles can apply more broadly, this is primarily a backend architecture book. It’s aimed at developers building microservices or modular monoliths who want systems that are easier to test, change, and understand.

Six chapters and an appendix are currently available through Manning’s Early Access Program, with new material added as the author continues writing. MEAP readers can read the book while it’s being developed and provide feedback that may help shape the finished edition.
