Rails callbacks are powerful… until they quietly stack up and turn simple operations into multi-minute transactions.

In this talk, we’ll dive into real-world lessons from working with a long-lived Rails monolith where years of callback layering created hidden behaviour, unpredictable performance, and sprawling execution chains.

Join us to learn:

🔍 How we identified the pain points
⚙️ How we traced performance bottlenecks
🧵 How we safely untangled the callback mess
🚀 Practical strategies for scaling and refactoring mature Rails systems

Whether you work on a monolith, maintain legacy Rails code, or simply want to avoid callback overload — this session is for you.
