He began his career in 2010 as an international tax specialist with a Big Four in Luxembourg before joining another consulting firm in 2012, to work in their Lille office as a corporate and tax lawyer. From 2012 to 2022, he worked as an in-house tax counsel in the retail sector (ID KIDS, PROMOD) and became the European head of tax law for a major player in the renewable energy sector (BORALEX).

He advises his numerous clients, companies and directors alike, on all the tax issues they face, and assists them in both their day-to-day and exceptional business requirements.
