Senthil Murugan
@senthilmurugan
DevOps Engineer specializing in AWS cloud, CI/CD automation, and infrastructure as code.
What I'm looking for
I’m a DevOps Engineer with 13+ years of overall IT experience and 6+ years of hands-on expertise in DevOps, Cloud Engineering, CI/CD Automation, Infrastructure as Code (IaC), and Cloud-Native Application Deployments on AWS. I design, implement, and manage AWS cloud infrastructure to support highly available and scalable enterprise applications.
I’ve built and optimized end-to-end CI/CD pipelines using Jenkins, GitHub Actions, and GitLab CI/CD, reducing deployment effort by 70% and accelerating release cycles from weeks to hours. I also implement IaC with Terraform and AWS CloudFormation to enable automated, repeatable, version-controlled provisioning—reducing manual configuration efforts by 80%.
I bring deep AWS and platform operations experience across Kubernetes (EKS), ECS, containerization (Docker), and observability with CloudWatch, Prometheus, Grafana, ELK Stack, and Splunk/Datadog—reducing incident detection and resolution times by 50%. I’ve migrated legacy applications (including .NET Core workloads) to AWS, improving scalability, reliability, and operational efficiency, and I’ve driven AWS cost optimization that contributed to a 30% reduction in cloud operational costs.
