Freelancer profile translated to English.

Description

Infrastructure architect with over 15 years of experience, mainly in international and multi-site environments.

I primarily work on on-premise infrastructures, with strong expertise in VMware, Windows Server, and Active Directory. I am involved in both the design and evolution of existing environments: infrastructure modernization, virtualization improvement, server security, and AD architecture structuring.

Accustomed to critical environments, I can provide advanced technical expertise or coordinate infrastructure projects involving multiple teams (systems, virtualization, network).

Areas of intervention:

• Design and evolution of Windows Server infrastructures

• Active Directory (design, migration, consolidation, GPO)

• VMware vSphere virtualization, storage, high availability

• Server environment security and optimization

• Technical project management of infrastructure projects

My approach is pragmatic: understand the context, propose a suitable solution, and implement it properly.
