With a very developer-oriented education, I specialised in Cloud and DevOps Engineering as I took an interest in automation and orchestration. My expertise got tailored around orchestration with Kubernetes, automation with different tools throughout CI/CD pipelines and a strong knowledge of cloud providers such as AWS and Azure.

Being tremendously passionate about computer science in general, I always keep myself up to date with the latest technologies. I also work on multiple personal projects ranging from web apps and self hosting to A.I which I am very passionate about.

I am looking for a role where I can leverage my experience to deliver while growing my technical expertise within a collaborative, forward-thinking and tech-oriented environment.

Employment History

DevOps Engineer at Societe Generale 2025 - 2026
• Designed and deployed scalable Kubernetes environments tailored to specific client application and infrastructure requirements. • Executed seamless migrations of workloads from legacy platforms to modernised cloud environments to improve maintainability and performance. • Drove targeted FinOps initiatives by analyzing client resource consumption and right-sizing Kubernetes workloads to match actual usage. • Audited existing infrastructure to identify and permanently decommission idle or unused servers, eliminating unnecessary compute waste. • Strategically migrated resources from expensive legacy infrastructure to newer, more cost-effective alternatives, significantly reducing overall cloud spend without impacting availability. • Led the migration of deployment pipelines from TeamCity to Jenkins, integrating GitHub webhooks, automating .NET application builds, and streamlining artifact publishing to JFrog. • Engineered Jenkins pipelines from scratch to replace legacy manual deployment steps, standardizing the release process across multiple projects. • Designed and implemented an end-to-end Infrastructure-as-Code (IaC) pipeline integrating Jenkins and Terraform for fully automated, zero-touch infrastructure provisioning. • Authored comprehensive documentation and onboarding guides for enterprise AI tools, test harnesses, and coding best practices. • Championed developer enablement by standardizing the use of internal AI resources, accelerating the onboarding process for new engineers across the company.
Site Reliability Engineer at Air Liquide 2023 - 2025
• Deployed and maintained multiple clients' Kubernetes workloads on Amazon EKS, ensuring high availability, autoscaling, and reliability across production environments. • Built and deployed infrastructure using Terraform and Terragrunt, including clusters, networking, and IAM policies. • Templatised and industrialised client resource deployments (applications, clusters, and custom infrastructure) via Foxops, reducing onboarding overhead and operational complexity. • Defined GitOps workflows with ArgoCD for environment segregation and automated reconciliation strategies. • Standardized versioning across platform components (clusters, monitoring stack) using Helm to improve maintenance, traceability, and overall industrialisation of the CaaS product. • Implemented continuous integration and build pipelines to support client migration to Kubernetes (containerizing workloads, integrating AWS SQS to monitor deployments). • Automated application delivery pipelines: built container images to AWS ECR, triggered AWS Lambda functions to provision ArgoCD projects, and committed manifests to GitLab for ArgoCD synchronization. • Automated end-to-end cluster bootstrap pipelines integrating Terraform, Helm, GitLab CI, and ArgoCD. • Developed an internal API for CaaS onboarding to automate the creation of GitLab groups and projects for application, infrastructure, and cluster deployments. • Implemented a comprehensive observability stack utilizing Prometheus, Grafana, Loki, and OpenTelemetry. • Built operational Grafana dashboards monitoring cluster health, application performance, infrastructure and workload resource consumption, and ArgoCD sync states. • Designed alerting rules targeting infrastructure anomalies, node lifecycle issues, Karpenter scaling events, and AWS Auto Scaling Group failures. • Acted as SRE Lead, onboarding new team members and mentoring them on tooling, internal workflows, deployment standards, and platform architecture.
DevOps Engineer at AXA Bank and Insurance 2022 - 2023
• Managed production releases and controlled change management across multiple environments (Qualification, UAT, PreProd, and Production) for high-impact applications. • Led the multi-tenancy migration of several enterprise applications to the Microsoft Azure Cloud. • Directed the migration of applications and infrastructure from Azure PaaS to OpenShift (CaaS). • Built and scheduled automated jobstreams utilizing WebJobs, E-GEN, and IBM Tivoli Workload Scheduler. • Ensured continuous operational maintenance, reliability, and performance optimization for critical production systems.
DevOps Engineer at Wavestone 2021 - 2022
• Establishment of a framing note to organise and clarify the steps needed to reach my objectives. It was also important as I provided a clear planning of all my future work throughout my internship • Creation of a "push" CI/CD pipeline from scratch using Jenkins and Github for the CI and Spinnaker for the CD • Creation of a "pull" CI/CD pipeline based on Github Action & ArgoCD/HELM • Comparison of the 2 pipelines based on their performance, features, use cases... • Setup Kubernetes Clusters using EKS & GKE • Automatisation of the Docker image generation, tagging and push in the Docker Registry (DockerHub & AWS ECR) and respective changes in HELM charts
DevOps Engineer at SIOPS 2020 - 2021
• Infrastructure provisioning through Terraform Cloud for easier and quicker creation of platforms for clients • Automatic configuration of client instances through Ansible for a secure and ready-to-go environment
Analyst - Cybersecurity & Digital Trust at Wavestone 2019 - 2020
• Development of a POC to test the implementation of a Customer Identity & Access Management solution (CIAM) • Developed 2 front-ends with Angular that were storefronts on which users could shop for items and activities • Setting up of 2 backends with NodeJS & Express to handle the items, the registering and the connection of the users through Okta's CIAM solution • Mise en place of a database with Sequelize (MySQL) to handle users and their data • Migration of users from basic user management towards CIAM
