Juan hails from Lima, Peru. He has earned a degree from San Ignacio de Loyola University as a systems engineer. Before starting his career as a web developer, he created, a service that let its users use Twitter via SMS in Peru (at that time that feature was US only). Taiper got quite popular, but it also had a short lifespan since smartphone use was on the rise. After a year and a half, Juan decided to shut down Taiper and start his web development career. While his work focuses on bringing the best experience to its users, his nonwork interests range widely, from solar panels to digital liberties. He would enjoy a nice chat about all of these topics. More info on how Taiper worked: Interview
