In the context of the health crisis, Antoine was able to make himself available and actively participated in the implementation of the infrastructures and services necessary for teleworking (OTP, securing infrastructures, support and support for users, production of user documentation, ...) Once again Antoine was able to demonstrate his availability and professionalism in a stressful context.

Since we have been working with him, Antoine has shown professionalism, initiative and perseverance. Also in the continuity of his work in setting up our SIEM, Antoine automated the integration chain of DOTNET application logs, set up alerts for prevention in the malfunction of applications and the detection of abnormal behavior. It is with pleasure that we will continue to work with him.
