One of about every 60 children in Israel has some form of autism. Some of these children require special attention and often need help navigating their school’s interior space to move from one room to another. After the “Yahdav” school had won the innovation competition with their brilliant idea, AT&T Israel accepted the challenge to implement an open-source solution for indoor navigation for kids. Numerous technologies such as GraphQl, nest.js and angular, as well as Unity and Kotlin, were used to develop this project with continuous integration while maintaining high code quality and speed of development. Collaboration between a large number of people made this project possible. This a story of success, technology and collaboration.
