As a Cloud & Network consultant for Skillx, I assisted several clients in the design, deployment, and security of their hybrid infrastructures. I worked on both on-premise and cloud environments (mainly GCP, Azure, and OCI), with a role covering architecture, migration, connectivity, and network security. My expertise led me to work on various topics: secure interconnections, segmentation, high availability, automation with Terraform and Python, and integration of Cloud best practices. These missions allowed me to develop a transverse vision of network and cloud challenges in demanding technical contexts.
