Architect and manage production Kubernetes and Red Hat OpenShift 4.x clusters across Development, Staging, and Production environments, maintaining 99.9% SLA. Led migration of 40+ microservices from community Kubernetes to Red Hat OpenShift, implementing OpenShift-native Routes and Security Context Constraints (SCCs). Managed OpenShift administration, including operator lifecycle management (OLM), zero-downtime upgrades, and node patching using Machine Config Operator (MCO). Designed and maintained Infrastructure as Code (IaC) using Terraform and Ansible for scalable and repeatable deployments. Built and optimized CI/CD pipelines using Infosys DevSecOps Platform, Jenkins, and GitHub Actions for multi-environment deployments. Implemented GitOps-based continuous deployment using Argo CD, improving deployment consistency and rollback capabilities. Created and standardized Helm charts for microservices, reducing deployment time by 45% across multi tenant clusters. Implemented observability stack using Prometheus, Grafana, Alertmanager, and Loki, enabling 95% proactive incident detection. Managed AWS ECR repositories with automated lifecycle policies, reducing container image storage costs by 30%. Enforced cluster-wide security policies including RBAC, OAuth2, TLS, CIS benchmarks, and network policies.

Designed, deployed, and managed production-grade Kubernetes clusters on AWS EKS, ensuring high availability and scalability for banking applications. Architected and optimized CI/CD pipelines using Jenkins, GitHub Actions, and GitLab CI/CD for automated build, test, and deployment workflows. Provisioned cloud infrastructure using Terraform and implemented configuration management using Ansible for consistent environments. Implemented GitOps workflows using Argo CD, reducing manual deployment efforts by 60% and improving reliability. Integrated Prometheus, Grafana, Alertmanager, and Loki for real-time monitoring, logging, and proactive alerting. Configured NGINX Ingress Controllers, DNS routing, and TLS termination to securely expose applications. Integrated DevSecOps practices by implementing SonarQube, Checkmarx, and Aqua Security within CI/CD pipelines.

Assisted in deploying and managing containerized applications using Docker and Kubernetes, supporting development and test environments. Created and maintained YAML manifests for Kubernetes resources including Pods, Deployments, Services, Config Maps, and Secrets. Monitored application health and cluster performance using kubectl logs, describe, and events to troubleshoot pod failures and resource issues. Automated routine operational tasks using Bash and Shell scripting, reducing manual intervention and operational errors. Supported CI/CD pipelines using Jenkins and GitHub for build and deployment automation. Collaborated with development and QA teams to ensure smooth application releases and environment stability. Used Git and GitHub for source code management and version control.
