Worked at major Brazilian law firms, focusing both on structuring investment funds and handling tax litigation. He also served as the head of legal for a prominent Brazilian economic group, assuming various significant positions, including managing the group’s litigation (covering tax, civil, labor, administrative improbity, and environmental cases) and the corporate department. Most notably, he played a crucial role during a period of severe institutional and financial crisis for the group, being the in-house lawyer responsible for the group’s judicial reorganization (at the time, the largest judicial reorganization in São Paulo). 

Thanks to his multidisciplinary work and extensive crisis management experience, he has earned the trust of his clients not only in legal matters where he has considerable expertise but also in broader legal strategy discussions.
