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.
Speaker:
Francisco De Grandis – Senior RoR Engineer at Svitla Systems.
