Born in Santana, São José dos Campos, in the Brazilian state of São Paulo, Reis began his career at the R10 Academy in Paraíba - the academy run by former Brazilian international footballer Robinho - before joining the academy of professional side Palmeiras in 2016 at the age of ten.[2]
He established himself as a key player for Palmeiras' youth teams, often captaining the sides he played in, and played in the final of the 2022 edition of the Copa do Brasil Sub-17. However, during the game he collided with a Vasco da Gama player and suffered a concussion as a result, needing to be taken to hospital after regaining consciousness on the pitch.[3] Following the game, Reis thanked fans on social media, stating that he was fine after the incident.[4] He signed his first professional contract with Palmeiras towards the end of the 2022 season, penning a deal through 2025.[2][5]
On 11 October 2023, he was named by English newspaper The Guardian as one of the best players born in 2006 worldwide, alongside former Palmeiras teammates Endrick and Luis Guilherme.[6][7]
