Design and deployment of a complete GitLab environment, including installation, configuration, and integration of GitLab Runners to support CI/CD workflows. Creation and maintenance of Docker images optimized for CI/CD and infrastructure provisioning pipelines. Design and implementation of GitLab CI/CD pipelines to automate the Ansible and Terraform deployment chain for infrastructure as code management. Development and maintenance of Ansible roles to automate system and application configuration. Installation and configuration of HashiCorp Vault (Unseal, Auth Methods, Policies...) for centralized secret management and its integration into CI/CD pipelines. Provisioning of Vmware resources (VMs, subnets, gateways) with Terraform. Writing technical architecture documentation (DAT) and supporting internal teams.

Integrated a team of 4 developers and a tech lead on a new project in the Geographic Information System domain for Enedis's IT department. Project: Automate the installation and configuration of the FME Server platform. As part of a project to industrialize the deployment of the FME Server platform, I designed and implemented a complete automation solution via a CI/CD pipeline based on GitLab. The goal was to simplify, secure, and make the installation of FME Server on different environments reliable. To achieve this, I integrated Vault for secure secret management, developed Ansible playbooks and roles to manage platform dependencies (ArcGIS, Oracle, etc.), automate binary downloads from JFrog Artifactory, and initialize and configure the platform via FME's REST API. Tasks Performed: Set up the architecture of repositories on GitLab. Creation of automation deployment scripts on GitLab CI/CD. Integration of Vault for secure secret management. Development of Ansible playbooks to automatically download binaries from JFrog Artifactory. Technical Environment: GitLab, Ansible, Vault, jinja2, Artifactory, REST API.

As part of an IT management service, my responsibilities included maintenance in operational condition of the infrastructure, L2/L3 support, production environment automation, application deployment, monitoring, and the implementation of CI/CD pipelines and industrialization tools. Project: Deployment of the Azure ARC solution on an on-premise infrastructure. As technical lead for a client, I managed the project to implement the Azure ARC solution on an on-premise environment entirely based on Linux. This project enabled the integration and centralized management of non-Azure machines via Microsoft's cloud services. Tasks Performed: Set up an Ansible node. Configure Ansible inventory. Generate an Ansible playbook for installing the Azure Connected Machine agent on Linux virtual machines. Create update groups for 'non-Azure' machines. Create deployment tasks. Technical Environment: Azure, Azure Arc, Ansible, PowerShell. Project: Migration to Zimbra 9. As part of an infrastructure evolution project, I upgraded the operating system from Ubuntu 16.04 to Ubuntu 20.04 to ensure compatibility with new software versions. This upgrade was followed by the migration to Zimbra 9. Tasks Performed: Analysis of the existing environment under Ubuntu 16.04. Operating system upgrade to Ubuntu 20.04. Backup and recovery of the source server configuration. Installation and network configuration of the new Linux system. DNS record configuration. Installation of the Zimbra 9 solution on the destination server. Synchronization and export of LDAP and SQL data. Validation tests and go-live of the new email service. Technical Environment: Debian/Ubuntu, Zimbra, SMTP, LDAP, MySQL, DHCP/DNS.
