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. **Speaker:** Francisco De Grandis - Senior RoR Engineer at Svitla Systems **Event details:** Date – 11 December Time: CDT \- 12:00 PM \|7:00 PM UA \| 6:00 PM PL \|11:00 AM MX \|11:00 AM CR\| 2:00 PM AR Duration - 1 hour (45 min. speech + 15 min.
