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.
