☝ TechOps with the following roles :

✍ Technical Architect - Cloud-native
✍ Site Reliability Engineer
✍ ITOps Engineer
✍ DevOps Integrator

☝ More than 19 years of experience in IT for diverse and varied clients in France and Luxembourg, specialized more particularly in OpenSource and Enterprise Middleware, I have often played the role of integrator of Dev needs and Production's pre-requisites.

In a world where "Cloud Computing" is constantly changing speed, my questioning is constant, which has earned me the privilege to be engaged in micro-services quite early in Europe.(~2014).

Once I had my finger in the gears of micro-services and CNCF solutions, I was able to compare and implement different “Platform As-A-Service” solutions such as OpenShift, Vanilla Kubespray, Konvoy, DKP, Rancher, or else again IBM, Amazon or Azure and thus put it into Production in Private and Public Clouds.

☝ Above all, not stopping at the infrastructure layer, the rise in the application layers is natural to me, analyzing the added value to services around these Platforms.

☝ Today at EBRC, thanks to my field experiences, I play the role of conciliator between the application and the internet, between the Developement and Production needs under PSF and PCI-DSS constraints supporting our Clients in their transformation.
