Abstract
Over the last five years, we have been on an extraordinary journey to create the new United Codes HQ, a data-driven Smart Building seamlessly integrated with Smart Cities. This innovative space serves as a living showcase of cutting-edge technology and boundless potential. From AI-driven insights to Retrieval-Augmented Generation (RAG), sensor data integration, and speech-to-text capabilities, as well as audio and video streaming and self-learning models, we've combined advanced technologies to reimagine the future of smart buildings. We call them wise buildings with a consciousness. Join me as I share our journey, the lessons learned, and our aspirations to make J.A.R.V.I.S from Iron Man come alive in any home!

Abstract
AI can build an app in minutes. Give it a prompt, and you get a frontend, backend, and database... all wired together. Pretty impressive. But would you deploy that in a real enterprise? Probably not. Because when it matters, we still care about security, performance, data integrity, and maintainability. And that is exactly where Oracle APEX and the Oracle Database shine. In this session, I will show how AI is changing the way we build with APEX, and how our role as developers is evolving with it. We are no longer just creating pages and writing code. We become designers, orchestrators, and validators of what AI produces. Using a World Cup prediction app as a running example, I will go from idea to a working application with AI in the loop. From data model, to PL/SQL API, to a full APEX app. You will see how AI agents can accelerate development, and where human expertise still makes the difference. This is not about replacing developers. It is about becoming a 10x developer with AI.
