Born in Lisbon, Baltazar started his career with local S.U. Sintrense after having already played youth football there. He then switched to Odivelas FC, representing both clubs in the third and fourth divisions and having his first adventure abroad with Dresdner SC in Germany's Regionalliga Nord. Baltazar started the 2003–04 season still abroad, playing in the English Football Conference with Margate. He returned to his country in the following transfer window, joining C.D. Fátima in the third level, then spent a further campaign in that tier with former side Odivelas. Baltazar's only experience in the professionals came in 2005–06, as he appeared in only seven division two matches for F.C. Barreirense and also suffered relegation. He subsequently returned to the lower leagues, representing Imortal DC, Abrantes F.C. – he split the 2006–07 campaign between the two teams – and Real SC. After another season abroad, with Digenis Akritas Morphou in the Cypriot Second Division, Baltazar returned to Portugal and joined G.D. Igreja Nova in the third division. In January 2010 he rejoined Sintrense in level four, retiring in June of the following year at the age of 34.
Coaching career
After announcing his retirement, Baltazar took up coaching, starting as assistant manager at his first club Sintrense. In the summer of 2012 he was promoted to head coach, guiding them to promotion to the third division. In July 2013, Baltazar was appointed at second level side Atlético Clube de Portugal. His stay was however to be short-lived, as he was relieved of his duties after only one month. Baltazar joined the Filipino national teamcoaching staff in April 2014, going on to work under Thomas Dooley. He returned to his country shortly after, signing with lowly Casa Pia A.C. as their manager. In March 2017, after only three months in charge of S.C. Olhanense in the second tier, Baltazar moved to the Cypriot First Division with AEL Limassol. Roughly one year later, in the same capacity, he signed with fellow league clubAPOEL FC. Baltazar returned to his country and its second division on 22 January 2019, being appointed at G.D. Estoril Praia. In June, however, he left to become part of the coaching setup at Nottingham Forest following the appointment of Sabri Lamouchi.
