Missions: Industrialize development, testing, and production environments. • Designed and implemented a standardized CI/CD pipeline (GitLab CI, Azure DevOps) for several critical applications (ERP, internal tools, agricultural APIs). • Automated environment provisioning using Terraform, with reusable modules for both AZURE and AWS. • Used Kubernetes (on-prem via Rancher and on AZURE with AKS) to orchestrate containerized services (APIs, ETLs, batch services). • Created custom Helm charts to simplify microservice deployment. • Deployed a centralized monitoring solution with Prometheus, Grafana, and Alertmanager. • Wrote Python scripts to automate recurring tasks (secret rotation, log cleanup, pod checks). • Trained an internal DevOps team (4 people) through hands-on workshops, pair programming, and technical documentation on Confluence. • Supported the implementation of FinOps best practices (cloud cost management, budget alerts on AWS/AZURE). • Integrated security and compliance tools into pipelines (SAST/DAST scans with GitLab, fine-grained IAM access management).

Missions: Support in modernizing the cloud platform and upskilling technical teams. • Used Kubernetes, Helm, Rancher, AWS EKS, and Terraform. • Orchestrated deployments via Helm to manage complex configurations. • Utilized Rancher for centralized Kubernetes cluster management. • Hosted clusters on AWS EKS with a focus on network resilience. • Resolved AWS VPC CNI limitations by adding Calico as the CNI. • Deployed infrastructure using Terraform. • Integrated GitLab CI for CI/CD with environment tagging and manual validation in production. • Set up comprehensive monitoring with Prometheus, Grafana, and Alertmanager, including Slack notifications. • Closely collaborated with development teams to adapt the architecture. • Implemented a centralized logging strategy using Fluent Bit + Elasticsearch to improve traceability and support. • Contributed to writing internal technical documentation and onboarding new DevOps engineers through hands-on workshops.

Missions: Redesign of the application infrastructure to containerize internal services and make them more portable and scalable using AWS ECS • Implemented an architecture based on AWS ECS (Fargate) to run application containers. • Built a complete CI/CD pipeline: Dockerization, build via GitLab CI, image storage in GitLab Container Registry, and automatic deployment to ECS. • Used Infrastructure as Code with Terraform to provision ECS, ALB, tasks, and IAM roles. • Managed secrets with AWS Secrets Manager. • Set up monitoring with AWS CloudWatch, including custom dashboards. • Collaborated with a team of 5 people (DevOps, cloud architect, security, project manager) and 6 backend developers.

⇨ MY MISSION: Set up, deploy, and maintain a system that offers customers who have submitted a claim to Enedis the ability to track the progress of their case and, if necessary, directly communicate with Enedis through an instant messaging feature. ⇨ MY MISSION: Assist Enedis' meter reading service in increasing the number of consumption index returns by offering a web solution to digitize self-reading cards. Field of Intervention: ➤ Creation of Dockerfiles for deploying FastAPI APIs on instances (Dockerfile, AWS EC2). ➤ Deployment of the Docker image on AWS ECR (Docker, AWS ECR). ➤ Setting up CI / CD with Github Actions (Git, Github). ➤ Creating a database via AWS RDS service (AWS RDS). ➤ Deployment of the React Typescript website on AWS Amplify (AWS Amplify). ➤ Setting up a network (AWS VPC). ➤ Setting up EC2 instances (AWS EC2). ➤ Configuring EC2 instances using Ansible (AWS EC2, Ansible). ➤ Deploying AWS infrastructure with Terraform (Terraform, AWS). ➤ Setting up CI / CD on Github Actions (Git, Github). ➤ Creation of a pre-commit hook enabling Local CI integration (Python, Pre-commit).
