About

I’m a software engineer with 20 years of experience in development. I’ve a strong experience in micro-service architecture, SaaS development, kubernetes deployment and CI/CD.

Having long been interested in how my projects would be deployed and maintained in operational condition, I acquired devops skills early on, in addition to my software architecture skills. Working with sensitive data since 2005, I have also a good awareness to security problematic and challenges that this imposes.

I’m working since 2017 at ARIADNEXT, software editor in SaaS of identity solutions.

After having been responsible for a digital identity project, I took over the role of tehcnical architect. As such, I set up a QA team and a devops team. With this devops team, and in collaboration with the infrastructure team, I built a new production as code platform, based on kubernetes.
