A 30-episode course on the Boundary-Control-Entity (BCE) architecture pattern is now complete, with each episode under 5 minutes. BCE organizes code into packages named after business responsibilities, split into up to three layers: boundary, control, and entity. The package tree alone shows what an application does, which helps developers understand structure without reading every file, and helps coding agents get the context they need from package names. Episodes cover naming conventions, component interaction rules, and applying BCE to CLI apps, AWS CDK, web components, and tests, using real projects like ebank (Quarkus, MicroProfile, Jakarta EE), the zsmith coding agent, and the zb build tool.
