[4] The following 25 February, he made his first team – and Série A – debut, coming on as a half-time substitute for Fernando Pileggi in a 0–2 away loss against Bahia.

[5] Pirani scored his first professional goal on 28 February 2021, netting his team's second in a 2–2 Campeonato Paulista away draw against Santo André.

[9] On 13 June 2022, Santos agreed to loan Pirani to fellow top-tier side Cuiabá until the end of the season,[10] with the move being effective on 18 July.

He scored on his club debut, netting a last-minute equalizer in a 1–1 home draw against Atlético Mineiro three days later,[11] but only featured in nine more matches during the competition, as Dourado narrowly avoided relegation.

After being requested to return to Santos' first team squad by head coach Odair Hellmann in December 2022,[12] Pirani featured rarely, and moved to Fluminense also in the first division on 23 February 2023, on loan until the end of the year.
