Jeroen Prinsen, 35 and Dutch, came to volunteer in Peru after leaving corporate finance in London. Prinsen has since been teaching, blogging and consulting.

His latest project, however, will catch the attention of expats and Peruvians alike: He created a Lima bus map. To be more precise, it’s a map of 12 recommended routes to get around Lima, called Rutas Recomendables. (Lima has almost 600 bus routes, Prinsen says.)
