**Build an AI-Infused Chat Bot with LangChain4j**

Add intelligent conversational AI in your Java application!
This presentation demonstrates how to build a production-ready chatbot from scratch using LangChain4j, progressing from basic chat functionality to a sophisticated AI assistant with memory, content moderation, document retrieval (RAG), and business integration.

**Speaker:** António Gonçalves (@agoncal)

I am a Principal Software Engineer at Microsoft living in Paris. I evolve in the Jakarta EE, Spring, Micronaut, Quarkus and now AI landscapes. From distributed systems to microservices and the cloud, today I help my customers to develop the architecture that suits them the best.

Aside from working for my customers, I write books (Java EE and Quarkus), I create online courses, I talk at international conferences (Devoxx, JavaOne, GeeCon…), I write technical papers, articles and I co-present on the Technical French pod cast called Les Cast Codeurs. I've co-created the Paris JUG, Voxxed Microservices and Devoxx France. For all my work for the community I have been made Java Champion.
