Specializing in the AWS platform, I work with the various stakeholders in your company to support them in their cloud strategy. I guide you at every stage of your projects to increase your organization's maturity in cloud adoption. I evaluate, build, and administer your AWS and hybrid infrastructures while respecting cloud best practices. I integrate the DevOps culture throughout my work, promoting agility, continuous improvement, automation, and process control. I work on topics such as 'Lift & Shift' migrations, replatforming to AWS managed services, containerization, and fully 'Cloud Native' architectures.
