Project: High Schools in the Auvergne Rhone Alpes Region Tasks: 1. Preparing technical procedures and conducting comprehensive audits of the IT infrastructure. 2. Configuring routers, switches, firewalls, and Wi-Fi systems for optimal performance and security. 3. Migration to the CISCO Meraki solution, preparing logical schemas(VLANs, IP, firewall rules) and physical (cabling, configuration) aspects. 4. Crafting robust automation scripts to streamline infrastructure management, covering MERAKI API, switch management across diverse brands (HP, D-LINK, HUAWEI, CISCO), AD, and RADIUS. 5. Implementation of the SolarWinds suite (utilizing NCM and Mapper dashboards) for effective supervision and automation, including the backup and export of configurations for approximately 6000 switches. 6. Proficient management of virtual machines on the Hyper-V hypervisor, coupled with reliable backup strategies using Veeam. 7. Configuration and meticulous management of AD (GPO, DNS, DHCP, Print Server), WSUS, and Radius, leveraging both Windows Server and Linux platforms. 8. Diligent resolution of client-raised tickets, providing expert Level 3 Support to ensure seamless operations and user satisfaction.
