Currently Sr DevOps and Cloud & Data Architect at Deloitte France.FR

James Melenge Diaz

Cloud architect and DevOps engineer

I design and run platforms across public clouds (AWS, GCP, Azure, Scaleway, Outscale) and on-premises: infrastructure as code, Kubernetes and delivery pipelines, with an eye on cost.

Typical delivery pathCode in Git goes through a GitLab CI/CD pipeline to Terraform, which provisions public clouds (AWS, Google Cloud, Azure, Scaleway, Outscale) and on-premises infrastructure (VMware, OpenShift, Linux). Kubernetes runs on top, and Prometheus and Grafana observe every environment.Git repositoryGitLab CI/CDTerraformPublic cloudsAWS, Google Cloud, Azure,Scaleway, OutscaleOn-premisesVMware, OpenShift,LinuxKubernetes: EKS, GKE, AKS, OpenShiftPrometheus and Grafana across every environment
A typical delivery path in my work: code, pipeline, Terraform, then Kubernetes on public clouds and on-premises.

About

10+ years of experience delivering digital transformation: planning, designing and running cloud, data, network and security solutions that drive business value, and leading migration projects from on-premises to the cloud.

Electronics, systems and telecommunications engineer turned cloud architect. Expertise in on-premises VMware, OpenShift, Linux and Kubernetes, and in public clouds (AWS, GCP, Azure, Scaleway, Outscale), with a focus on infrastructure as code, containerization and secure, scalable architectures.

Trained at IMT Atlantique and HEC Paris. Fluent in Spanish, French and English.
