About Salah-Eddine

Network & Telecom Engineer, I support companies on architecture, integration, automation, and reliability of critical infrastructures. My background has led me to work on both Data/IP environments and operator VoIP platforms, giving me a transverse view of the network, from transport to services.

I work on routing and network engineering issues around BGP, OSPF, MPLS L3VPN, Multi-VRF, switching, load balancing, proxying, as well as automation with Python, Perl, Ansible, and Cisco NSO. I have also worked on migration, standardization, security, and observability topics, with a production, quality of service, and maintainability oriented approach.

What I bring to my clients is true technical autonomy, the ability to quickly understand existing environments, produce clean and usable deliverables, and drive a project from end to end: analysis, design, configuration, automation, validation, documentation, and production deployment. I have a strong appetite for modern network environments, particularly SDN, SD-WAN, automation, virtualization, and telecom architectures with high availability requirements. This last part is a coherent projection of your target positioning, but it relies more on your skills and training foundation than on missions explicitly detailed in my CV.
