"Barboza.... called her Chasers ‘talentless hags’, a comment he later insisted had been taken out of context."
-- from the Daily Prophet's coverage of the 2014 Quidditch World Cup tournament (Pm)
Having unwisely spoken to journalist Rita Skeeter before the tournament, an ongoing feud ensued between Barboza and his Welsh counterpart, Gwenog Jones, after he called her Chasers "talentless hags." Jones promised to curse his face off - and successfully did so - after Brazil beat Wales in the quarter-finals. However, thanks to efforts of the Healers, Barboza's skin was almost fully regrown later that day (Pm).
Barboza was praised in Ludo Bagman's feature article in the Daily Prophet for finding and bringing together such a young and talented Quidditch side. Having won their matches against Haiti, Wales and the USA, they lost in the final to Bulgaria after a spectacular Snitch capture by Viktor Krum (Pm).

José is the Portuguese and Spanish version of the name Joseph, which derives from Latin Ioseph, via Greek Ιωσηφ (Ioseph), and ultimately from the Hebrew name יוֹסֵף (Yosef), meaning "he will add" (Behind the Name).
Barboza is the Portuguese variant of the Spanish surname Barbosa, which is a geographical/topographic name from barba ("a type of plant") plus oso ("place rich in this plant") (Ancestry).
As he comes from Brazil, Barboza may have attended the Castelobruxo Wizarding School.
