My project mentor and I first defined the features and possible implementation. I then sketched a prototype and began app development. We discussed how new timers would be created, controlled, and how web browsers would show them. By taking turns programming through live screen sharing, we gradually built a working timer. I then designed UI screens; added admin authentication; created a 'custom' timer option with multiple, sequential timers; and wrote extensive code to check for errors and provide clear user feedback.
