The 2nd part hands-on workshop, in transition from SOLID to CuteDDD code.

Most real-world codebases share the same symptoms: bloated controllers, anemic models, cross-cutting concerns tangled together, and a growing gap between business language and the code that's supposed to reflect it.

In this workshop, we'll tackle a realistic Spring Boot + JPA legacy codebase — mixing too many concerns in a single monolithic model — and progressively reshape it using CUTE DDD: a pragmatic framework where design decisions are Contextual, language is Ubiquitous, models are Testable, and code is Expressive.

No slides-only theory. You'll read real messy code, run tests, review the code and refactor incrementally — leaving with concrete techniques you can apply on Monday morning.

Participants will go through the full DDD journey: from Event Storming and Domain Storytelling to identify Bounded Contexts, to Context Mapping to clarify boundaries, and finally to tactical patterns — Value Objects, Aggregates, Ports & Adapters, and making illegal states unrepresentable.
