In the public sector, he served as State Attorney of São Paulo for over ten years and as clerk at the Superior Court of Justice (STJ), working on significant cases before the Supreme Court (STF) and the STJ. He received the “Estado em Juízo” award for his work before the STF, which generated billions in savings for public coffers.
