I am committed to the energy transition, and I am convinced it represents a massive business opportunity. I have a thorough understanding of the challenges of decarbonisation.Capitalising on my skills in strategy, finance and project management, I cover the entire project development phase, from origination to commissioning. I am coordinating study phases, legal and financial structuring, major project contracts negotiation (concession, construction, operation, power purchase agreements), raising capital and debt and, more generally, negotiating with public parties (Public-Private Partnerships).I have a solid operational experience at international level, particularly in uncertain, volatile and complex environments.Specialities: Project finance - Capital raising - Business Development - Investments - M&A - Renewable energies - Energy transition - Decarbonisation - Emerging countries - Africa - Infrastructure - Managing Director - IPP - - Lithium - Critical Raw Materials - Geothermal energy
