About Sylvain

Seasoned IT executive, I combine permanent management mandates (CIO, CTO / COO IT) with transition & advisory missions for SMEs, mid-sized companies, and large international groups. Expert in the transformation, security, and industrialization of information systems in contexts of growth, merger, restructuring, or cyber crisis.
I sustainably align IT organizations with business challenges: governance, cybersecurity, cloud, data, AI, and I bring solid experience in corporate IT environments (finance, purchasing, HR, CRM, ERP, ITSM) to serve performance, compliance, and operational resilience.
