Back to original languageAbout Alexandre
Passionate about IT since my early age, a developer since I was 7, I have made IT my profession. My 18 years of experience have allowed me to build expertise in system administration and VoIP, including knowledge of the relevant French legislative aspects.
Independent for 6 years, I support my clients by offering them according to their needs: consulting, training, project management, development, and system administration. For example, I work on migrating a service platform for an operator, which involves advising on design, developing, testing, documenting, deploying, and providing support (level 2 and 3). My recent missions have partly involved the following technologies: GCP, AWS, Azure, VMWare On Premise, Proxmox, XCP-ng, Tower, Ansible, PostgreSQL, MySQL, S3, Keycloak, WireGuard, GitLab including CI/CD, NetBox, Grafana, Prometheus, Redmine, Git, Kubernetes, Docker, Postfix, Zimbra, Carbonio, O365, ISPConfig, PowerDNS, Firewalld, FreePBX, Asterisk, Debian, Ubuntu, Nginx, PHP, Python, Ruby.
