Strategic Consultant – Transformation, Organization & Public Sector
With over 15 years of experience in organizational leadership and strategic consulting, I support leaders, local authorities, and companies in their transformation, development, and complex situation management projects.
Founder of the Casyma firm, I specialize in:
• Strategy and Governance: defining direction, repositioning, project management.
• Organization and Performance: reorganization, process optimization, change management.
• Public-Private Partnerships: negotiation, structuring, and operational management.
• Environmental Transition: circular economy, resource management, sustainable development.
My experience bridges the public sector (local authorities, operators) and the private sector (SMEs, mid-sized companies, investors), with a pragmatic and results-oriented approach.
I favor tailor-made interventions, combining strategic vision with operational capability.
