Career
Born in Barreiro, Carreira interested in basketball was sparked by a cousin, who took him to Barreirense, where he started competing at age 9. In 1997, he started his professional career in the basketball section of telecommunications company, Portugal Telecom, staying for one season, before moving to Seixal. In 2002, the 23-year-old had his first spell at his hometown club, Barreirense, representing them for one year, before returning to Seixal for a second stint, in the season immediately after.
In 2004, he moved clubs again, joining Barreirense for a second time, again for just one year, as he left for Belenenses on 15 June 2005.
In 2008, Carreira moved to, helping in the resurgence of the Eagles, winning multiple league and cup titles, and competing in European basket in the 2010-2011 and 2014-2015 editions of the EuroChallenge. In August 2009, Carreira was one of the first Portuguese to contract H1N1, in a outbreak that started in the club youth ranks.
Less than a year later, he was diagnosed with a benign tumor, adjacent to his right ear. After it was surgically removed, Carreira made a full recovery.
