H2O software engineer Martin Turoci gives a live coding demo of H2O Wave, a Python framework for building web-based AI apps without writing HTML, CSS, or JavaScript. Starting from an empty project, he builds a working app with buttons and text input, shows how to browse Wave's example gallery, and demonstrates theming and deployment options. He also shares that H2O's own Hydrogen Torch UI was built by data scientists with no web development background in two to three weeks.
