- Developed standardized CI/CD templates across projects using GitHub Actions and Argo CD.
- Managed AWS WAF and ALB, optimizing protection and response times.
- Enhanced production security and improved access control by implementing role-based access control (RBAC) and network policies with Calico in Amazon EKS.
- Built CI/CD pipelines using GitHub Actions and Argo CD, reducing deployment effort by 45% and improving delivery speed.
Senior DevOps Engineer
ARKAS Line
- Architected Jenkins pipelines for microservices using Docker, doubling release speed.
- Monitored Kubernetes clusters using Prometheus and Grafana, reducing mean time to repair (MTTR) by 30%.
- Containerized legacy apps and implemented GitOps for modernized delivery.

Experience
Large-scale Kubernetes Cluster Deployment
I also integrated Argo CD and Jenkins to build a robust CI/CD pipeline with automated testing and GitOps-based deployment. I deployed the Istio service mesh for intelligent traffic routing and observability and configured auto-scaling and AWS load balancers to ensure performance under peak loads.
This architecture increased system availability to 99.99%, reduced infrastructure costs by 30%, and scaled traffic handling capacity fourfold without downtime.
