With a degree in public business law complemented by business school studies, I began my career as in-house counsel at VINCI Construction France and then at SYSTRA. I subsequently practiced as a lawyer at the firms FTPA Avocats and Frêche & Associés before joining LexCase in 2026. Admitted to the Paris Bar in 2022, I work as an associate lawyer in the Major Projects department, headed by Raphaël Apelbaum.

My practice focuses primarily on public business law and public and private construction law (court-ordered expert assessments, contractual and legal guarantees, financial settlement of contracts, and disputes with subcontractors and joint contractors).

I represent the firm’s clients in both advisory and litigation matters before administrative and judicial courts.
