๐ What is this about?
A practical, one-dayย workshop where your development team will learn how to refactor an application using Clean Architecture principles.
Delivered at 3 international events, including SymfonyCon 2025 (Amsterdam)ย โ selected via CFP, rated 4.67/5 by participants.
Unlike typical trainings that rely on trivial “to-do” apps, weโll work with the Conduit, a RealWorld Example App; a full-featured blogging platform (Medium-like) that reflects the challenges of real systems.
๐ฏ 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.
