Automation passionate, from infrastructure architecture to continuous deployment of applications, I use Clouds & best to your needs technologies to enhance your processes & build highly available, resilient & secure infrastructures.
My domains: Automation, DevOps, Architecture, Cloud, Performance, Continuous improvement.

I help my customers to improve their cloud adoption, implement best practices, help them to build their cloud strategy and infrastructure.
I’m certified AWS Solution Architect and SysOps, but I work also with GCP, Azure and private clouds to best fit my customers technical and business needs.
I went really deep in the knowledge of container technology, at low level with system implementation as high level with orchestration.
I had big experiences with Kubernetes and Openshift and also passed my Kubernetes Administrator Certification.
I worked a lot with Terraform, Puppet Ansible and others automation tools for small needs in little companies as for industrial needs in big companies for multi-environment multi business-units infrastructures.
For my customers and myself, I have always been in a continuous improvement mindset and I have always been learning to understand in depth what I’m working with.
I always tried to have various experiences and get out of my confort zone in order to improve my expertise, face new things and transform my knowledge into experiences.
For customers needs and to share with the community I give trainings (AWS, Terraform, Puppet…) and conferences.
Past years I worked as a consultant for different companies, and worked on building highly available, resilient and secured infrastructures.
I helped my customers to improve their processes and to approach automation for infrastructure and continuous deployment the best way to fit their business and technical needs.
The different experiences I had taught me to be very close to my customers needs and to be able to well understand this ones, implement them the best way and be able to explain the solutions simply.
I can also build and give training to your teams.
