Caluza, who began skating on
roller blades at age six, took up figure skating when he was seven following the roller rink's closure. Caluza won the bronze medal at the 2012
Bavarian Open and at the same time earned the minimum score necessary to compete in an ISU Championships. He went on to place 12th at the
2012 Four Continents Championships and 21st at the
2012 World Championships. The Philippines used the
2013 Four Continents to determine who would receive their sole men's spot at the
2013 World Championships. Caluza finished 14th, ahead of
Michael Christian Martinez, and was sent to Worlds, where he finished 34th. == Personal life ==
