What I'm looking for

I am looking for a role that allows me to further develop my skills in network management and telecommunications, ideally in a collaborative environment that values innovation and growth.

As an Expert at DHD, I provide Level 2 support for the deployment of routers, switches, and Wi-Fi access points, ensuring that clients receive the best service tailored to their subscription needs. My journey in the telecommunications field began with a strong educational foundation in Computer Science, specializing in System and Network Administration.

Prior to my current role, I served as a technician at Orange Business Services, where I assisted in the deployment of BVPN and BIE routers and switches. My experience includes a significant internship at Orange Madagascar, where I focused on implementing an authentication server and supervising configurations for Cisco routers. This hands-on experience has equipped me with the necessary skills to excel in the fast-paced world of telecommunications.
