The three developers, along with a 35-year veteran of the NYSE who had never coded before, built three Twilio-powered apps in just hours, including an app that lets users contact their congressional representative via SMS and another that provides real-time stock prices through text messages. The team's creation was made possible by the NYSE's Code Jam event, which brought together developers to build innovative applications using Twilio technology. The apps were built with a focus on community engagement and social impact, with one of the apps even featuring a hotline where users can call "Hodor" and be put on hold by the fictional character from Game of Thrones.
