"Managing I/O at Scale With Netty", by António Pedro, Backend Developer at Devexperts

About the Talk
Modern distributed system need to handle massive number of concurrents connections and a large volume network I/O without compromising its performance and system reliability. In this talk we will uncover how Netty's event-driven I/O, event loops, non-blocking networking, and efficient memory management makes that possible.We will explore core Netty concepts and how they fit together at scale. Along the way, we will take look at common performance pitfalls such as backpressure and connection management.

"Blindfolded in Production: Uncovering the Black Box of Conversational LLMs", by Luís Maia, AI Specialist and Tech Leader at BrightFactory

About the Talk
In the playground, LLMs behave. In production, real users ensure the "happy path" disappears in minute one. Running a healthy conversational AI system is no longer just about prompt engineering; it’s a pure observability challenge. When an Agent hallucinates on the 5th user interaction, how do you pinpoint exactly which retrieved document or tool call poisoned the context? In this session, we will dive into the anatomy of production chaos for multi-turn LLMs. Drawing from real-world experience at BRIGHTFactory, we’ll show how to move past "vibe coding" guesswork and implement true span-level telemetry and tracing.
