The brief

From the day-to-day corporate to the sophisticated deal.

A corporate lawyer with a career built entirely within Corporate Law and Contracts, with strong exposure to Capital Markets and M&A.

From day-to-day corporate housekeeping — corporate acts, books, governance — to sophisticated matters such as shareholders' agreements, holding structures, succession planning and fundraising. Experience spanning a publicly-listed company's IPO, investment agreements and structured operations at a startup, due diligence, and CVM (the Brazilian SEC) compliance.

Fit: in-house legal (corporate) or law-firm roles across Corporate, M&A, Contracts and Capital Markets, at mid-level (Pleno).
