"Infrastructure should no longer be a cost center, but a growth driver."
Certified Kubernetes Expert(**CKA**, **CKAD**) with a background focused on critical infrastructures (Schneider Electric), I intervene to transform technical complexity into operational and financial performance.
I don't just sell execution, I bring a strategy to secure and make profitable your Cloud & Hybrid environments.
💡 My Added Value in 3 Points:
- **💰FinOps (-30% Azure costs)**: Invoice optimization and rightsizing.
- 🚀 **DevEx Acceleration**: -70% build time via ephemeral agents.
- 🛡️ **Resilience**: Zero Downtime Architecture on hybrid clusters.
🎯 Areas of Intervention:
1. Cloud & FinOps Strategy
- Cost audit and Azure invoice optimization.
- Usage control and budget definition (Quotas, Tagging).
- Rightsizing Kubernetes resources to stop waste.
2. Kubernetes Architecture & Modernization
- Roadmaps for scalable hybrid infrastructures (Azure AKS & On-prem).
- Migration to aGitOpsapproach (ArgoCD).
- Complete ecosystem: **Kubeadm, Helm, Kustomize**.
- Infrastructure as Code (IaC): **Terraform & Ansible**.
- Unified observability: **Prometheus, Thanos, Grafana, Loki**.
3.DevEx & Supply Chain Security
- CI/CD chain optimization (Jenkins, GitHub Actions) with ephemeral agents.
- Container security (Vulnerability scans, Trivy, Patch Management).
- Mentoring technical teams.
📜 Certifications & Background:
- CKA (Admin) & CKAD (Dev)
- AZ-900 (Microsoft Azure Fundamentals)
- Master's in Computer Engineering (Grenoble Alpes).

Experience
- Schneider ElectricDevOps/SRE & FinOps Consultant | Kubernetes (K8s) & Azure ExpertENERGY AND UTILITIESJanuary 2025 - Today (1 year and 5 months)Grenoble, FranceContinuing my collaboration with Schneider Electric, I now act as an independent expert to lead critical projects related to scalability, cost optimization, and security.
Key Achievements:
- **FinOps & Cost Management**: Cloud resource optimization (pod rightsizing) leading to a **direct 30% reduction in unnecessary infrastructure costs**.
- CI/CD & DevEx Optimization**: Redesign of the build chain for complex environments (Yocto). Implementation of builds on **ephemeral Kubernetes agentsin the cloud, ensuring infinite scalability and drastically reducing developer waiting times.
- Migration & Architecture**: Orchestration of critical service migration between Kubernetes clusters and implementation of **Configuration as Codestrategies to unify the management of Dev and Prod environments.
- **Supply Chain Security**: Securing Docker images through the creation of automated inventories, continuous vulnerability scans, and the implementation of an automated patch management pipeline.
- **Cloud Provisioning**: Leading Infrastructure as Code (Terraform) for dynamic provisioning of Azure Cloud resources.
**Impact**: > A more agile infrastructure, enhanced security by default, and complete control over Cloud consumption. - Schneider ElectricDevOps/SRE & Kubernetes Consultant | Hybrid Infrastructure ExpertiseENERGY AND UTILITIESSeptember 2021 - January 2025 (3 years and 4 months)38000, Grenoble, FranceAs a Cloud Architect and SRE, I led the design and evolution of critical infrastructures for Schneider Electric, focusing on Cloud/On-Premise hybridization and high availability.
Key Achievements:
- **Hybrid Roadmap & Architecture**: Defining the technical roadmap for interconnection between Azure Landing Zone and on-premise infrastructures. Deployment of Kubernetes clusters (Kubeadm) managing network, persistent storage, and high availability.
- **Infrastructure as Code (IaC)**: Complete standardization via Terraform and Ansible, ensuring full reproducibility of production environments.
- **Observability at Scale**: Design of a distributed monitoring stack (Prometheus, Thanos, Grafana, Loki) for proactive visibility across multi-site systems.
- **CI/CD Acceleration**: Optimization of Jenkins agents/GitHub runners on the fly on Kubernetes, reducing build times by 30%.
- **Training & Documentation**: Creation of runbooks and training of internal teams on GitOps practices and Kubernetes operations.
Business Impact:
- **Scalability**: Elimination of build queues and absorption of load peaks through K8s agent auto-scaling.
- **Reliability**: Proactive incident detection and reduced recovery time thanks to advanced observability.
- CabrilogDevOps/SRE ConsultantPUBLISHINGSeptember 2020 - September 2021 (1 year)38600, Fontaine, FranceThis foundational experience allowed me to master the complete automation of application and infrastructure lifecycles up to deployment, essential bases for my current SRE expertise.
Key Achievements:
- **"As-Code" Automation**: Creation of a scripting framework (Bash) for complete server provisioning (Docker, Monitoring, Security) from A to Z.
- **Orchestration & Containerization**: Setup of isolated environments using Docker Swarm + Jenkins → build reduced from 30 min to 7 min (-77%).
- **Fullstack Awareness**: Development of internal monitoring interfaces (VueJS/Firebase) to provide teams with real-time visibility on Jenkins builds.
- **Cloud CI/CD**: Automation of deployments to Azure with an efficient test environment management strategy.
**Key Skills**: Docker Swarm, Jenkins CI/CD, Azure, Bash Scripting, VueJS.
