Executive summary
I designed and operated a production Amazon EKS platform with hardened RBAC and CI/CD-driven deployments — sustaining 99.99% uptime, cutting unauthorized-access incidents by 50%, and speeding container deployments by 40%.
The problem
- Containerized workloads needed a secure, scalable orchestration platform that could hold up under real production traffic.
- Access control was too coarse, leaving room for unauthorized access across namespaces.
- Manual deployment steps slowed releases and introduced inconsistency.
The solution
- Designed and maintained containerized applications on Amazon EKS with Docker and Helm.
- Implemented least-privilege RBAC and network policies to tightly scope access by namespace and role.
- Drove deployments through Jenkins and GitLab CI/CD for consistent, repeatable releases.
- Instrumented the platform with Prometheus and CloudWatch for proactive incident response.

Engineering challenges
Least privilege at scale
Designing RBAC that's tight enough to be safe yet workable for teams shipping daily across many namespaces.
Reliability under load
Sustaining 99.99% uptime meant resilient scheduling, autoscaling, and fast, observable recovery.
Consistent delivery
Replacing manual steps with CI/CD removed drift and made deployments boringly reliable.
Outcomes & impact
Sustained on production EKS workloads.
Through hardened, least-privilege RBAC.
Faster container deployments via CI/CD.
Scoped by namespace and role.
