Back to original languageAbout Chahine
I support companies in setting up efficient, secure, and automated infrastructures to gain reliability, performance, and peace of mind!
What I can bring you:
- Setup and optimization of CI/CD pipelines (**GitLab, Jenkins**) to accelerate your deployments.
- Management of Cloud & On-Premise infrastructures (**OpenStack**, **OVH, Scalingo, AWS, Azure**) with an Infrastructure as Code approach (**Terraform, Ansible**).
- Securing and monitoring your systems (**NetworkPolicies**, **Cyberwatch, F5, Fortinet, Grafana, Prometheus, Centreon, ELK, SSO Keycloak**).
- Containerization & orchestration (**Docker, Kubernetes**) for better scalability.
- Implementation of a GitOps approach (**ArgoCD, Rundeck**) to make your environments more reliable.
- Good command of databases (**MariaDB, MongoDB, PostgreSQL/CNPG**) and task automation via scripts (**Bash, SQL, Python, YAML**).
My added value?
Beyond the technical aspects, I bring pedagogy, benevolence, and transparency. My goal is not only to deliver arobustsolution but also to enable you tounderstandit,masterit, and make it **evolve**.
Types of projects I regularly work on:
- Cloud Migration
- Security and monitoring of critical environments.
- Deployment of Kubernetes clusters and process automation.
- End-to-end DevOps support, from architecture to production.
Passionate about new technologies, but also about history and Brazilian Jiu-Jitsu, I look forward to discussing with you and discovering your project!
