João David Ribeiro Pais Ferreira is the 2015 Portugal Monopoly Champion and competed at the 2015 World Championship in Macau in September 2015.

João's bio from the 2015 World Championship Press Kit:

João (25 years old) has been playing MONOPOLY since he was very young, young enough that he can’t remember how old he actually was when he started playing! He only owns one classic board — his favorite version of the MONOPOLY game. His strategy can’t be planned out; he says his strategy is different for each game that he plays. He enjoys using his mathematical skills to manipulate his opponents.
