[10] Pie joined the Centro de Iniciación Deportiva Escolar (CIDE) led by Isaac Ogando, where he were signed after his participation in the 2012 National Elementary School Games,[8] practicing track and field with the coach Francisca Tiburcio when he was ten but later the coach Héctor Rodríguez helped him to switch to Taekwondo one year later.

[14] Two years later, after he won an Olympic bronze medal in Rio 2016, a controversy burst about Pie's nationality, especially in social media.

[7][19] Pie won the 2013 Bolivarian Games silver medal in the 58 kg category after 16-17 falling to the Colombia Luis Muñoz in the final contest.

[23] He thanked his teammates and coaches when he won the gold medal in the qualifier mixing different technics in front of every fighter of the 63 kg category.

[25] Soon after that, Pie won the gold medal in the Santo Domingo Open, when he defeated the Mexican Abel Mendoza[26] helping the Dominican Republic to reach the second place in the event.

[28] After this series of victories, Pie was said to be one of the main figures and biggest medal hopes for his home country by the Dominican Republic Taekwondo Federation president, Francisco Camacho.

[29] He won the 58 kg Central American and Caribbean Games gold medal recovering from a last minute tie kick from silver medalist the Venezuela Mario Leal.

[35] The president of the Dominican Republic University Sports Commission, Vice Minister Marcos Díaz regretted that the Pan American Games were taking place at the same time of the 2015 Summer Universiade, because the nation had to prioritize the first ones, not being able to count with Pie representing his home country.

[41] He later confessed that lack of international warm ups before the games affected his level of fighting, because of the quality of rivals that he had to face in the preliminary rounds.

[40] After the regional games, Pie was invited for his ranking points,[40] to take part in the WTF World Grand Prix Series held in Moscow, falling to the Portuguese Rui Bragança in the first contest 5–6 in the 58 kg[42] Pie lost 11-13 once again to the Mexican Navarro in the Pan American Open WTF G1 in Aguascalientes, winning again the silver medal.
