Born in Setúbal, Quinito played in exactly ten Primeira Liga seasons during his professional career, making his debut in 1967–68 with Académica de Coimbra – having moved to Coimbra to study medicine at the university– but he only appeared in eight league games over the course of two full seasons. He also represented C.F. Os Belenenses (six years) and S.C. Braga (two), retiring in 1980 at nearly 31 with top level totals of 193 games and 11 goals.
One year after retiring, Quinito started coaching with his last club Braga, being fired after the 13th round of the 1981–82 season. Until the end of the decade he worked exclusively in his country's top flight, reaching the fourth position in 1984 with precisely the Minho side.
Quinito started the 1988–89 campaign at the helm of FC Porto. Even though the team collected no losses in the first 11 games they only won five, and he was relieved of his duties as the northerners eventually lost the title race to S.L. Benfica; the manager also spent three seasons in the second level, notably achieving promotion in 1996 with his very first club as a player, Vitória de Setúbal.
After the ninth round of 1997–98, Quinito replaced fired Jaime Pacheco and led Vitória de Guimarães to the third position, with the subsequent qualification to the UEFA Cup. It was his second spell at the Estádio D. Afonso Henriques, following the fourth position of 1995.
