Refactoring towards clean architecture workshop πŸ«§πŸ›οΈ

πŸ“š What is this about?

A practical, one-day on-site workshop where your development team will learn how to refactor an application using Clean Architecture principles.

Performed at SymfonyCon 2025 (Amsterdam)Β β€” selected via CFP and delivered as a full-day workshop.

Unlike typical trainings that rely on trivial “to-do” apps, we’ll work with the Conduit, a RealWorld Example App; a full-featured blogging platform (Medium-like) that reflects the challenges of real systems.

🎯 Outcomes

By the end of the workshop, your team will:

  • Decouple business logic from the implementation details (like framework code),
  • Improve testability and long-term maintainability.
  • Understand and know how to apply Clean Architecture (not just in theory),
  • Know the patterns, tools, and strategies to refactor legacy systems with confidence.
