About Zachary

Specialized in high-voltage electrical infrastructure, I work on projects related to electricity transmission networks, underground and submarine cable systems, and network equipment.

During my experience on interconnection projects, renewable energy connections, and electricity grid development, I have acquired expertise in defining technical specifications, qualifying equipment, and monitoring tests and material production.

I have also conducted techno-economic studies and preliminary designs for complex electrical infrastructures. These projects often involve strong interaction with other trades and infrastructures (existing underground networks, civil engineering, connection of industrial or tertiary clients with varied constraints), which has allowed me to develop a transverse and coordinated vision of infrastructure projects.

I now offer consulting and technical support missions on energy and industrial infrastructure projects: technical studies, compliance analysis, electrical equipment qualification, design review, or owner's engineer support.
