Career
He represented his nation Portugal in three editions of the Olympic Games (2000, 2008, and 2012), and has been training throughout his sailing career for Cascais Naval Club (Portuguese: Clube Naval de Cascais) in his current residence Cascais, under his personal coach Andy Zawija. Despite missing out a place on the Portuguese team in Athens 2004, Domingos returned from an eight-year absence to compete for his second bid at the 2008 Summer Olympics in Beijing. Sailing with skipper Bernardo Santos in their new boat Star, the Portuguese duo started the race on a blistering third-place effort, but fell short to eighth by a late caution in the middle of the series with a score of 72 Netto points.
Domingos and Melo failed to improve their feat from the previous Games throughout the ten-race series with a mediocre, fifteenth-place effort, posting a Netto grade of 108.
