Designed and implemented multi-stage CI/CD pipelines in Jenkins, Azure DevOps, and GitHub Actions for microservices deployed on AWS (EKS, EC2, S3, Lambda) and GCP (GKE, Cloud Build). Managed Docker containers and orchestration in Kubernetes (EKS, AKS, GKE); Helm charts, RBAC, NetworkPolicies, Ingress controllers, and image scanning. Automated infrastructure with Terraform and CloudFormation in multi-cloud environments; managed configuration with Ansible and remote state. Administered Linux servers (Red Hat, Ubuntu, CentOS); systemd, cron, networking, and scripting in Python, Bash/Shell, and PowerShell. Monitored and observed with Prometheus, Grafana, and ELK/EFK; alerts, dashboards, and incident response runbooks. Implemented DevSecOps practices in pipelines: SonarQube, Trivy, Snyk; managed secrets with Vault and AWS Secrets Manager, SSL/TLS certificates, and hardening. Managed Git repositories with GitFlow in GitHub, Bitbucket, and Azure Repos; semantic versioning, release control, and artifact management with Nexus/Artifactory. Collaborated with engineering teams to support releases, identify bottlenecks, and improve efficiency in development, staging, and production environments.

Built and maintained CI/CD pipelines in Jenkins and Azure DevOps for Java and Node.js applications; automated builds, testing, and deployments on AWS and Azure. Managed Docker containers and deployments in Kubernetes (EKS, AKS, OpenShift) with private registries (ECR, ACR); image scanning and security policies. Implemented Infrastructure as Code with Terraform and Ansible; provisioned VPCs, subnets, security groups, and load balancers in multi-cloud environments. Monitored with Prometheus, Grafana, and ELK; resolved production incidents autonomously. Applied DevSecOps with SonarQube, Trivy, and secret management with Vault. Administered Linux (Red Hat, Ubuntu); hardening, systemd, cron, and networking. Collaborated with cross-functional teams and documented processes.

Designed and maintained CI/CD pipelines with Jenkins (Groovy), Azure DevOps (YAML), and Bitbucket Pipelines; automated testing, static analysis, and blue/green and canary deployments. Managed Docker and Kubernetes (EKS, AKS) in development, staging, and production; Helm charts, Ingress controllers, and network policies. Implemented IaC with Terraform, Ansible, and CloudFormation; automated server provisioning, clusters, and networks on AWS and Azure. Administered Linux (Red Hat, Ubuntu, CentOS); systemd, cron, DNS, and load balancing. Scripted in Python, Bash/Shell, Groovy, and PowerShell. Monitored with Prometheus, Grafana, and ELK; centralized logs and alerts. Integrated SonarQube and Nexus/Artifactory for code quality. Scanned Docker images for vulnerabilities; managed secrets with Vault, SSL/TLS, and hardening. Managed Git repositories with GitHub, GitLab, Bitbucket, and GitOps workflows.
