I also master backup and restore solutions with Veeam, supervision and monitoring with Centreon, Nagios, Dell OpenManage Enterprise, iDRAC and CloudIQ, as well as the administration and security of network and system infrastructures.
My experience also includes managing SQL Server, Oracle, MySQL, MariaDB, and MongoDB databases, integrating enhanced authentication mechanisms like MFA, and automating tasks via PowerShell and shell scripts. I have led several strategic projects for the migration, evolution, and security of critical infrastructures, ensuring performance, high availability, and business continuity.
