## Talk 1: GONG & Agentic AI Tools

Gong built an agentic AI solution called Claude Code to help developers work more effectively across its complex microservice architecture of over 100+ repositories. Using a multi-agent system with specialised rules, skills, and subagents, it automates development tasks and reduces time spent on research and context switching. The result is faster development and better pattern compliance, reducing complex tasks from days to hours. Join Vanja Tesin to discover how.

## Talk 1: Resilience in Microservices

In the distributed landscape of modern backend architecture, the question isn’t if a service will fail, but when.
Without robust fault tolerance, a single latent dependency can trigger a cascading failure across an entire ecosystem.
Anthony's talk will focus on how Gong overcame some of those challenges and how they are implementing resilience utilising patterns such as Circuit Breakers, Rate Limiters and others to maintain stability and provide graceful degradation even when downstream services are under duress.

DubJUG 265, our live in-person event, presents Professor Ž (aka Željko Kozina!) Hear why Netflix dumped REST in favour of GraphQL and explore how memory management improves performance, the different parts of Java memory and the various garbage collectors.

## Talk 1: Netflix dropped REST, but should you?

Last year, Netflix announced that it was dropping REST completely in favour of GraphQL. It is undoubtedly one of the popular kids on the Development playground right now.

GraphQL is a new way to build APIs, one that's easier, faster, better, and more flexible than the old RESTful API system, or at least that's the promise.

In this session, a REST developers' Assessment of Spring GraphQL, Željko will cover the basics of Spring GraphQL, explore its strengths and weaknesses, and determine whether it is a better option for your company than a conventional REST API.

## Talk 2: Trash Talk - Optimising Java Garbage Collection

Understanding how Java organises memory is important for every Java professional, but this particular topic is a common knowledge gap for many software professionals.

With the help of Željko, this talk explores how memory management can help you improve performance effectively, helping you understand the different parts of Java memory and the various garbage collectors so you can select your preferred one.
