Alfredo was born in Vila do Conde. After emerging through the youth system of hometown's Rio Ave F.C. he went on to represent Boavista FC, being an undisputed starter for the latter for more than a Portuguese first division decade.
After his retirement in 1998, at nearly 36, Alfredo served as goalkeeping coach for his last club as it achieved its only national league conquest in 2001. During his playing spell with the Porto side he won four major titles in the 90s, two Portuguese Cups and as many domestic Supercups.
In the 2009–10 season, shortly after leaving Boavista, Alfredo returned to his first team Rio Ave, again being in charge of its goalkeepers. He also worked in that capacity with CS Pandurii Târgu Jiu in Romania.
