To have a global view of the infrastructure, I decided to implement supervision solutions and pay more attention to security.

• Implementation of a Fortinet VDOM to isolate certain application environments

• Configuration of eBGP and Creation of remote access VPNs with a Fortinet client

• Configuration of 7250-IXR and 7750-SR7 routers (Nokia Router)

• Configuration of a VPLS and a VPRN for the isolation of deployed virtual machines

• Deployment of a Proxmox VE infrastructure in cluster with Ceph distributed storage (redundancy, fault tolerance, scaling).

• Implementation of a complete supervision solution with Zabbix (adding hosts, creating custom templates, dashboards). In addition to zabbix, an uptime KUMA tool for a quick view of the infrastructure.

• Writing technical documentation and operating and installation procedures.

• Technologies: Nokia SROS/SRLinux, HPE, Dell, Fortinet, VLAN, N2/N3 support

Context: As part of the continuous improvement of our service's IT infrastructure, we have implemented several security solutions, including:

• Deployment of LaaS infrastructure services to customers.

• Comparative study of hypervisors, choice of the optimal solution, implementation with storage management.

• Complete migration of a datacenter between two buildings. Completion of a preliminary analysis, planning, transport, reconfiguration, and commissioning with zero critical interruption.

• Extension of IT infrastructures to support scaling. Addition of servers, routers, and switches, redesign of connectivity, and implementation of VXLAN and IP/MPLS for interconnection.

• Strengthening datacenter security. Design of service bubbles, implementation of flow matrices, centralization of access (sso), and network segmentation.

• Writing and maintaining technical operating documentation.

• Implementation of site-to-site VPN links according to business uses. Optimization of connectivity between sites, particularly via alternative connections. Technologies: VPN Fortinet, Starlink

• Management of daily network and security support. Configuration and troubleshooting of equipment, handling of N2/N3 incidents, and administration of the LAN in a production environment.

• Technologies: Nokia SROS/SRLinux, HPE, Dell, Fortinet, LAN, SNMP, N2/N3 support

• Active participation in interoperability test campaigns on 4G and 5G networks, in real conditions, with multi-brand mobile terminals. Implementation of test scenarios and validation of network behaviors in a complex operator environment.

• Identification of malfunctions and request for corrections from R&D teams.

• Validation of advanced LTE-A/5G NR features

• Contribution to client sessions for the validation of services and mobile terminals, in connection with pre-sales engineers and product teams.

• Preparation of test platforms, execution of scenarios, and writing of technical reports
