KEN ROTARIS
Full-Stack Developer
Hello, I'm Ken, a Swiss systems-focused software engineer with 7+ years of experience in backend development, web technologies, and DevOps. I work on Java-based systems and modern infrastructure, with a strong focus on automation and maintainable code. I care deeply about structure and clarity, designing systems so intent is clear at the top and complexity is revealed gradually.
Key Accomplishments
- Stabilized and standardized an unstable Jenkins CI/CD landscape by introducing versioned Jenkinsfiles and a shared library, retiring 200+ legacy scripts and reducing build times by up to 5x.
- Designed and implemented automated OpenShift deployments using Jenkins, Helm, and GitOps tooling (ArgoCD), enabling consistent, declarative, multi-service deployments with rollback-safe configuration management.
- Implemented and maintained 20+ Jenkins pipelines across Windows and Linux, working closely with ops and external teams to resolve build failures, credential management, and cross-platform execution issues.
