About Cedric

Systems Engineer at Blue (Bretagne Telecom) for 5 years.
I work daily on a very wide range of technologies and in complete autonomy (from VM creation to Firewall rules, including LUN management on our infrastructure). This allows me to be agile and multi-task.

However, I have affinities with Citrix/Veeam and Wallix technologies.

Having several years of support experience, I consider myself quite adept at debugging and incident analysis.
