Description

Looking to accelerate your Cloud and DevOps projects while upskilling your teams? This is exactly what I offer.

💡 My role: transforming your technical challenges into concrete, robust, and sustainable solutions.

🔧 My expertise (non-exhaustive list):

• Kubernetes: deployment, operation, and optimization of large-scale clusters,

• GitOps with ArgoCD: implementation of automated and reliable pipelines,

• AWS Cloud: architecture, migration (e.g., moving from Heroku to AWS), cost optimization,

• CI/CD: design of fluid integration and deployment chains,

• Support & training: sharing DevOps best practices for autonomous teams.

🌍 Why work with me?

• A pragmatic vision of DevOps: technology should serve your business objectives, not the other way around,

• The ability to intervene in both strategic consulting and operational implementation,

• A true culture of knowledge transfer: I train your teams to gain autonomy.

📍 Availability: in-person in the Rennes area and the Saint-Malo region, or fully remote anywhere in France.

👉 Let's work together to bring speed, reliability, and value to your Cloud & DevOps projects.
