Design and implement end-to-end DevOps architecture to support scalable and reliable applications. Designed, managed, and optimized CI/CD pipelines using Jenkins for continuous software delivery across multiple cloud platforms. Automated deployment and configuration management using Ansible and Docker, ensuring consistency and reducing manual intervention. Deployed and maintained microservices and applications on Kubernetes clusters across AWS, Azure, IBM Cloud, and Oracle Cloud. Managed and automated infrastructure provisioning for 20+ environments and 3000+ servers using Terraform and Ansible. Defined SRE metrics such as SLIs, SLOs, and error budgets, ensuring reliable and observable production systems. Enhanced system observability using Prometheus, Grafana, and the ELK stack, resulting in a 40% reduction in Mean Time to Recovery (MTTR). Ensured cloud governance, cost optimization, and high availability across hybrid cloud environments.

Implemented GitOps practices using Argo CD to streamline application delivery on Kubernetes. Developed Jenkins pipelines to automate build, test, and deployment workflows cutting down release time by 60%. Managed cloud infrastructure through Terraform modules, promoting code reuse and environment standardization. Automated configuration changes using Ansible, reducing manual provisioning errors. Ensured seamless cloud operations across AWS and Azure, including service integrations and access control. Containerized and orchestrated applications using Docker and Kubernetes. Reduced AWS cloud spends by 25% through reserved instance planning and resource optimization. Designed multi-cloud failover strategy that improved system reliability by 99.99%.

Administered and monitored 100+ Linux servers (RHEL, CentOS) ensuring uptime, patch compliance, and security hardening. Automated repetitive sysadmin tasks using Bash scripting, reducing manual workload by 70%. Responded to P1 incidents, performed root cause analysis, and drove system recovery procedures. Handled virtualization and backups using VMware tools, ensuring infrastructure stability. Collaborated with support teams and clients for scheduled maintenance and change management.
