Your degree Tecnólogo em Análise e Desenvolvimento de Sistemas listed in the Anabin database, which is used to compare foreign degrees to German ones. This database is checked by immigration officers when you apply for a blue card.
For your degree it lists the equivalence class
Bedingt vergleichbar: Bakkalaureus/Bachelor 3j
which means it's only partially comparable to a German 3 year Bachelor.
According to the German residence act, § 18a Abs. 1 Nr. 1 an applicant can only get a blue card if
a) holds a German or a foreign higher education qualification which is recognised or otherwise comparable to a German higher education qualification
(Emphasis mine). A partly comparable degree is not enough by the words of the law.
This interpretation of the law is shared by the Federal Minstry of the Interior and laid down in the various administrative regulations, e.g the Baden-Württemberg one.
Additionally to the degree, the school or university needs to be listed in the database as "H+" to recognize the degree.
Any applicant can send their degree to ZAB first, which (for a fee) will compare the individual case to the German education system and issue an official statement.
Even if the path to a blue card is not open, it is of course still possible to get a work permit with less requirements (but it's harder to obtain them).
