Svitla Smart Talk. When Callbacks Hurt: Scaling Rails in a Large Monolith

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.
