About Jean-David

Throughout my various experiences, I have indeed evolved in a very complete environment. However, the training I chose is that of a network security engineer. During my past experiences, my skills in this area have developed with Orange Business Services, Airbus, and Vedecom.

In my last experience, I worked as a network expert for the implementation of the network architecture of the Evaps project. I would be delighted to explain to you in person what the subject is about in detail. Being the network reference for the project, I was the only person capable of configuring the equipment and networking it to establish secure communication.

During my time at Airbus, I was in charge of securing the network that the team and I set up. Firewalls, update patches, clean stations, and OS hardening were part of my daily routine.

My mission at Orange was difficult at first, due to the multitude of software to know. That said, it was more pleasant for me to communicate in English with the on-site teams, taking control of the equipment and operating the troubleshooting. During this mission, there was a lot of configuration verification and router settings. The addressing plans were already specified upstream by level 3, so our team only had to enter the commands or verify the configurations to be integrated on the equipment so that they could resume service.

All these experiences make me a profile that can adapt to any type of environment, which makes me all the more effective for the client's pleasure.
