19:30 – 20:00 Q&A, Wrap-up.
Talk 1: Large Language Models and their role within the current Search & AI ecosystem
Speaker: Afonso Mendes
Talk Summary: This session looks beyond the buzz to question what large language models (LLMs) truly bring to the table, and where their limits lie. We will examine how these models fit within the broader ecosystem of Search and AI tools and how they relate with more traditional systems. From uncovering where LLMs shine to exposing where they do not, the discussion invites a clearer view of their real value in today’s landscape.
Other talks to be submitted soon! If you’d like to join and present at this meet-up, please get in touch with Bernardo or Carlos!

Hacking the Stack: Using OpenSearch Dashboards as an Application Framework
Most developers treat OpenSearch Dashboards (OSD) strictly as a visualization layer—a place for charts and graphs. They are missing the bigger picture. OSD is a powerful, untapped environment for full-stack application development. In this session, we peel back the architecture of an enterprise-grade risk, compliance, and security platform built entirely on top of OSD. We moved beyond simple plugins and pushed OSD to its limits to create a seamless, interactive application experience.
Join us for a deep dive into the engineering reality of the OpenSearch stack, including:

The Analysis: Why the OpenSearch stack beat out the competition.
The Build, Beyond Visualization: How to implement custom React components to build complex workflows and interactive UIs within OSD.
The Integrations: Integrating Wazuh for agent management and ingesting data at scale.
The “Gotchas”: Honest, real-world lessons on data handling, state management, and what to look out for.

If you are ready to push your plugins from “reporting tools” to “robust software,” do not miss this session!
