About Chahine
J’accompagne les entreprises dans la mise en place d’infrastructures efficaces, sécurisées et automatisées pour gagner en fiabilité, en performance et en sérénité !
Ce que je peux vous apporter :
- Mise en place et optimisation de pipelines CI/CD (GitLab, Jenkins) pour accélérer vos déploiements.
- Gestion d’infrastructures Cloud & On-Premise (OpenStack, OVH, Scalingo, AWS, Azure) avec une approche Infrastructure as Code (Terraform, Ansible).
- Sécurisation et supervision de vos systèmes (NetworkPolicies, Cyberwatch, F5, Fortinet, Grafana, Prometheus, Centreon, ELK, SSO Keycloak).
- Conteneurisation & orchestration (Docker, Kubernetes) pour une meilleure scalabilité.
- Mise en place d’une démarche GitOps (ArgoCD, Rundeck) pour fiabiliser vos environnements.
- Bonne maitrise en bases de données (MariaDB, MongoDB, PostgreSQL/CNPG) et automatisation de tâches via scripts (Bash, SQL, Python, YAML).
Ma valeur ajoutée ?
Au-delà de la technique, j’apporte pédagogie, bienveillance et transparence. Mon objectif est non seulement de délivrer une solution robuste mais aussi de vous permettre de la comprendre, de la maîtriser et de la faire évoluer.
Types de projets sur lesquels j’interviens régulièrement :
- Migration Cloud
- Sécurisation et monitoring d’environnements critiques.
- Déploiement de clusters Kubernetes et automatisation des process.
- Accompagnement DevOps de A à Z, de l'architecture à la production.
Passionné par les nouvelles technologies, mais aussi par l’histoire et le Jiu-Jitsu brésilien, j’ai hâte d’échanger avec vous et de découvrir votre projet !
