Thanks to Nicolas, I was able to finalize the setup of our production environment and improve my skills in setting up highly scalable infrastructures on Amazon AWS. Despite the tight timing, he was able to make himself available in the money time and even helped us integrate an administration monitoring server to monitor in real time the performance of our back office in a high availability perspective.

Once again, very good job both on the implementation of the mission and on Nicolas' ability to propose simple technical solutions to implement. His technological watch has allowed us to save a lot of time and gain skills on the latest technologies.
