Began orienteering in 2006 at the age of 14, in a project named Nature School. It was very important for the orienteering career of De Siqueira Chiles, because without it she would never have met orienteering, since the sport is not very known in Brazil. State Champion in 2009 and second in the South American O Champs (W18E). South American Champion in 2010 (W18E). First national senior title in 2011 (W20E). Brazilian and South American Champion in 2014 and 2016 and second place in the South American Championships in 2015.
