Building an AI-Copilot like system + Spring Boot 4

We’ve got two great talks lined up for our March meetup. Dudu from Cato Networks will show how they built an AI Copilot–style system for their users, including lots of under-the-hood details. Yaniv from AT&T will walk us through the new Spring 4 features we can’t live without.

Thanks to Cato Networks for sponsoring and hosting the event!

AGENDA

18:00–18:30 Mingling, food, and drinks
18:30–18:40 Opening words
18:40–19:25 No Hallucinations Allowed: Running AI in a Live Enterprise System / Dudu Oliel - Cato Networks
19:30–20:15 Spring Boot 4: The Good, the Bad and the Ugly / Yaniv Nahoum - AT&T

No Hallucinations Allowed: Running AI in a Live Enterprise System
In this session, we'll explore how we built a production-grade AI Copilot for the Cato Management Application (CMA). The copilot is deeply integrated with our application stack and APIs, allowing it to understand product context and assist users with both knowledge-based and account-specific questions. The system is implemented using Spring AI, enabling structured integration with LLM providers, prompt orchestration, and seamless alignment with our existing Java ecosystem. During the talk, we walk through the system architecture, how we provide a reliable application context to the LLM, and how we translate user intent into meaningful actions and insights. I'll share the engineering challenges we faced in production — including reliability, observability, debugging LLM behavior, and continuously improving answer quality. Finally, we'll cover the lessons we learned from running a customer-facing AI system inside a live enterprise environment, where accuracy, trust, and stability are non-negotiable.

Spring Boot 4: The Good, the Bad and the Ugly
Is Spring Boot 4 a developer's dream or a migration nightmare? Every major release brings a mix of innovation and friction, and this talk peels back the curtain on the latest iteration. From the sleek new modularization and powerful HTTP Service Clients to the disruptive transition to Jackson 3, we evaluate what helps and what hurts. We will discuss how to implement robust API versioning, achieve better null-safety, and survive the migration process without losing your sanity. Whether you’re excited for the new features or dreading the upgrade, this session provides the roadmap you need for the road ahead.

Yaniv Nahoum / AT&T
Yaniv Nahoum is a principal engineer and technical coach at AT&T Israel R&D Center, guiding and helping developers reach their full potential by increasing developer velocity. Yaniv has been working with Java and the JVM for almost two decades - writing code, delivering workshops, and consulting teams on countless JVM-related topics, from generics and concurrency to tuning for latency and throughput in production. He's married and a proud father of two, and when he's not reading, writing, or talking about code - you'll find him running, a lot!
