CoderDojo Braga is a nonprofit initiative run by CeSIUM (the Computer Engineering Student Center at the University of Minho) that has been in existence for ten years and aims to teach programming to children and young people ages 7 to 17. In these sessions, the Ninjas—the participating children—are challenged to solve various computer science problems based on their level of knowledge, always with the support of Mentors (volunteers with the initiative).
