18:30 Intro by Host Neciu Dan

18:45 Dealing with memory leaks in production
Speaker: Asier Aduriz Saiz, Lead Frontend Engineer @Sim Local

Have you ever experienced declining performance on your site, but haven't been able to identify the root cause? This talk presents SimLocal's (https://simlocal.com/) real-world situation, where the frontend experience initially degraded for no apparent reason. We'll examine the entire journey, from detection, what didn't work, mitigation, and what ultimately led to the fix for the memory leak.

19:20 Practical guide to animation in React
Speaker: Kateryna Porshnieva, Engineering @ Buffer, Public Speaker

Small animations can make UIs more delightful and improve user experience. In this talk, we’ll explore how to add these animation to your React apps, using everything from simple CSS transitions to more complex spring-based motion.
We'll walk through practical examples to show how these animations can enhance user experience without getting in the way. Plus, we'll discuss how to keep them running smoothly and make sure they're accessible to everyone.

19:50: Drinks and networking!
