Please note: The building locks after 6pm -
The building locks for individuals who park outside of the onsite garage after 6pm, so we recommend arriving at the meetup start time of 5:30 or using the onsite garage if you are running late.

If you park in the onsite garage, attendees can access floor 7 with no restrictions after 6pm.

💭 Talk Abstracts:
Observability and SLOs with Elastic - Rajesh Sharma

This session will show how to move from “we have metrics/logs/traces” to reliable, measurable user experience by defining and operating Service Level Objectives (SLOs) in the Elastic Stack. We’ll cover how to translate business expectations into SLI/SLO definitions, instrument services with Elastic Observability (APM, logs, metrics, synthetics), and use Kibana to track error budgets and detect fast-burning reliability issues before they become incidents. Attendees will leave with practical patterns for choosing meaningful SLIs, setting realistic targets, and wiring burn-rate alerting and dashboards that align engineers and stakeholders around outcomes.

Key takeaways:
- SLO fundamentals: SLIs, targets, and error budgets (what to measure and why)
- End-to-end observability: correlating APM + logs + metrics + synthetics to explain SLO misses
- Operationalizing reliability: error-budget reporting, burn-rate alerting, and actionable runbooks in Kibana
- Adoption patterns: starting small, iterating targets, and avoiding vanity metrics

Demo: “Checkout API SLO in 10 minutes”
A small “Checkout” HTTP endpoint (e.g., POST /checkout) instrumented with Elastic APM, plus a synthetic test that runs the checkout flow every minute.

Build your own Developer Advocate with DeepAgent Justin Castilla (Sr. Developer Advocate at Elastic)

Staying current with emerging frameworks is exhausting and can be swayed by bias. New repositories appear daily, each claiming to solve our problems better than the last. How do we separate the signal from the noise?

In this session, we'll walk through building a multi-agent research system using LangChain's DeepAgents framework. The system uses specialized SubAgents to evaluate technology viability: one tracks GitHub metrics (stars, commit velocity, contributor health), another analyzes issues and discussions for red flags, and a third synthesizes findings into actionable recommendations.

You'll learn how DeepAgents' built-in planning tools, filesystem backend, and sub-agent delegation handle the complexity of parallel research tasks. We'll cover practical patterns for context isolation between agents, when to spawn SubAgents vs. handle tasks inline, and how to persist research findings across sessions using composite backends.
Walk away with a working architecture you can adapt for your own technology vetting workflows.
