In this weekly livestream series, Ted M. Young and I build an AI-powered role-playing game using React, Spring Boot, and Nullables. And, of course, plenty of discussion about design, architecture, and effective programming practices.

Watch us live every Monday! For details, see the event page. For more episode recordings, see the episode archive.

Our new stream! We explain the goals of the project—to create an AI-powered role-playing game—then get to work. Our first task is to create a Nullable wrapper for the OpenAI service. The work goes smoothly, and by the end of the episode, we have an OpenAiClient that sends POST requests to the service.
