Project: Modernization Context: Piloting the migration and of a Legacy infrastructure (3 Proxmox Standalones) to Nutanix distributed across two sites, aiming to eliminate technical debt and customer services. Main achievements:

• OS Migration & Modernization: Complete refactoring of 15+ servers, including critical upgrade from Debian 5/6 to Debian 12 and conversion of legacy services (init.d to systemd) to ensure sustainability and compatibility.

• Infrastructure as Code (IaC) & Automation: Deployment of a configuration management strategy via Puppet (driven by Bitbucket), ensuring maintenance, automated package deployment, and server standardization.

• Container Orchestration: Migration and security of Docker Swarm clusters (Manager + 3 Workers) integrated into a Git workflow with Nginx Reverse Proxy, for better application scalability.

• Documentation & Standards: Writing complete technical documentation (Operating Procedures, Installation Guides) in French and English, facilitating handover and maintainability.

• Migration of 23 Centreon 7.x servers to RHEL 7.10 then 8.10 (CV, CCV, AK, and Modop)

• Participation in writing and presenting operational sheets and technical architecture documents

• INFOBLOX Gris Manager Administration: creating routes, DNS and reverse DNS, IPAM

• Implementation of a Linux base model for ZABBIX monitoring

• Implementation of a RedHat migration procedure from 6 to 7, 6 to 8, and 7 to 8.

• Implementation of an action plan, batching, and application of a project in Auditbeat

• IBM FS5200 storage administration for SAN disk management.

• Implementation of commissioning and decommissioning procedures (PTE and CMDB)

• Handling of N2, N3, and N4 vulnerabilities, OPENSCAP scanning and generation of remediation playbooks

• PCI-DSS AUDIT, Hardening, implementation of security solutions

Environment: Linux Redhat 6, 7, and 8, AIX 5, 6, and 7, Satellite 6.7, Foreman, PULP (repos, etc…), Ansible, VMWARE VCENTER, Shell BASH and ksh, ITIL V4, PCI-DSS, Hardening, REMEDY, ZABBIX

• Within the Production department, we are responsible for the proper functioning, control, and optimization of the production environment, and we manage production deployments and testing environments.

• We also proposed IT redesign and DEVOPS transformation.

• Participation in defining architectures (configuration, sizing, and DAT) and their implementation

• INFOBLOX: VLAN, DNS (Private, Public), IPAM Administration

• Updates and migration of over 1463 physical and virtual Linux servers to facilitate patching for the CDS, and standardize the security level: updating DAT.

• Handle all vulnerability levels generated by QUALYS and write resolution procedures for N1 and N2.

• Work upstream with commissioned PCI audits to validate security standards at ACCOR, then update HARDENING procedures.

• Incident management: SAN, filesystems mounted on SAN disks, LUN, allocation and verification

• Participation in migration projects from OPENLDAP to IDM: as part of the standardization of all accounts with cloud accounts.

Environment: Nutanix Converged Infrastructure, KVM and AHV, Nexus, Linux Redhat 6, 7, and 8, Satellite 6.7, Ansible, Docker, GIT, CI/CD chain (GITLAB), VMWARE VCENTER, Shell BASH, TALEND, Privitar, Cloudera, SPLUNK, ELK, AWS Cloud, ITIL V4, Cloudamize, PCI-DSS, QUALYS, over 4000 servers in INFRA.
