He has significant experience in tax litigation and dispute resolution. He regularly represents clients in high-stakes tax controversies, both in administrative proceedings and before Belgian and international courts.

He also acts for private clients, including business owners, executives, and high-net-worth individuals, advising them on wealth structuring, succession planning, and cross-border tax issues.
He advises a diverse clientele ranging from innovative start-ups and scale-ups to multinational groups and high-net-worth individuals, often facing complex tax challenges or undergoing strategic transformations.
His practice primarily focuses on clients operating in the technology and media, life sciences, and real estate sectors.

In 2022, he published a book titled La responsabilité des pouvoirs publics en matière fiscale (Larcier), a groundbreaking analysis of government liability in tax disputes, which is already cited as a reference work in the Belgian legal landscape.
