Max Firtman is a mobile and web developer based in Buenos Aires, Argentina. PhoneGap is an open source framework that allows building cross-platform mobile apps using HTML, CSS, and JavaScript. It works by packaging web apps so they can be deployed and run as native mobile applications. PhoneGap supports many mobile platforms but each still requires separate compilation. Debugging mobile web apps can also be challenging. The speaker provides advice around maintaining a single codebase, embracing platform differences, and focusing on performance and the best experience for each context.
