About Sylvain

Business lawyer with international experience, I handle issues related to contracts, legal structuring, and compliance for organizations and individuals. My role is to provide a clear, coherent legal framework adapted to operational realities.

I specialize in drafting and reviewing various legal documents (supplier contracts, NDAs, T&Cs, governance policies, etc.), assisting with regulatory compliance (especially GDPR), and providing legal analysis for projects requiring precise framing. Expertise in technology law is leveraged if your challenges involve digital, data, or IT aspects.

I favor a rigorous and pragmatic approach: identifying issues, presenting options, and producing usable documents. The goal is to provide an understanding of legal issues and actionable support, without unnecessary complexity.

If you have a project or a question, I would be delighted to discuss it with you. Conversations can be held in French or English.
