Back to original languageAbout Salim
I am Salim Klikhat, a Network and Security Engineer with over 10 years of experience in designing, integrating, and operating complex network and security infrastructures, primarily within large telecom operators and demanding B2B environments.
I have worked with major players such as SFR Business and Bouygues Télécom Entreprise, where I participated in the end-to-end validation of DATA offerings (L2VPN, L3VPN, MPLS, Datacenter, SD-WAN Fortinet), technical qualification of solutions, and N2/N3 support in critical environments.
My expertise covers:
advanced routing (BGP, OSPF, ISIS, MPLS, VXLAN/EVPN),
network security (Fortinet, Cisco ISE, IPsec/SSL VPN, 802.1X),
operator and enterprise LAN / WAN / DC architectures,
BUILD, RUN, and technical pre-sales phases.
Accustomed to working at the interface between sales, technical, and vendor teams, I know how to translate client needs into robust, industrialized, and secure solutions. I also work on setting up labs, reproducing incidents, HLD/LLD documentation, and task automation (Python).
