Estefanía Ortiz, a Hackathon fan and young entrepreneur, grew up in the town of Guaynabo Puerto Rico and went to the Marista private school for most of her schooling. Estefanía finished her last high school year doing home schooling, and today she is a sophomore majoring Computer Science at Stanford University.  Estefanía told me that a transformational moment in her life was a conversation she had with her math teacher.
