Back to original languageAbout Liwa
Senior DevOps Engineer (6+ years, CKA certified) specializing in CI/CD pipeline industrialization and DevSecOps approach. I support development teams by automating continuous integration and deployment, from artifact building to production deployment, to deliver faster and more securely.
My expertise: Jenkins (Groovy Shared Libraries), GitLab CI, GitHub Actions, Docker, Kubernetes, Helm, Rancher, as well as integration of quality and security tools (SonarQube, Fortify, Checkmarx, Nexus). I work on .NET, Java, JavaScript, and Python environments.
What I can offer you: CI/CD pipeline design and standardization, creation of reusable Shared Libraries, hardening and optimization of Docker images, Nexus governance, and technical support for teams as a Tech Lead.
I have managed shared CI/CD platforms serving multiple teams and dozens of projects in the banking and insurance sectors (Generali, Arval BNP Paribas, ODDO BHF).
I work 100% remotely and prioritize missions focused on build, industrialization, and CI/CD automation (rather than production operations or support).
