Ezzine trained in the practice of business litigation and arbitration with several major French and Anglo-Saxon law firms, where he also had the opportunity to deal with various business law issues, such as economic and corporate law, both in litigation and business advising.
He holds a Master 2 in International Economic Law from the University of Paris 1 Panthéon-Sorbonne, and has thus placed the international perspective at the centre of his career after having obtained the CRFPA (French Bar Exam) following his Master 1 with a specialisation in international and European law.
He has a particular expertise in private and public international law in the context of international litigation.
Ezzine has been practicing boxing since the age of 9 and football since he was a child. He also has a particular interest in trekking, which he had the opportunity to do in Indonesia when he climbed a volcano at 3,800 meters.
He is interested in the emancipation of young people through knowledge and sport, and actively participated in the creation of an association in the 15th arrondissement of Paris called "La Bonne Equipe" of which his brother is a founding member.
