Domain-Driven Transformation—Modularizing and Modernizing Legacy Software

Starting a new project from scratch with a clean slate is one thing; tackling legacy systems with chaotic architectures is another. Many teams inherit systems described as “Monoliths” or “Big Balls of Mud,” and this talk focuses on how to bring order to such challenges.

Participants will learn how to evaluate their current systems and identify steps to introduce—or restore—structure. Using Collaborative Modeling, attendees will gain actionable insights to design a clear and future-ready architecture.

The talk will equip participants with practical strategies to address common challenges, such as BBOM architecture, anemic domain models, and disorganized teams. By the end of the session, attendees will have a catalog of proven refactorings, actionable heuristics, and concrete tools to immediately evolve their own projects.
