Kumar Mangalam

I’m an AWS DevOps Engineer with 2+ years of production experience building scalable, secure cloud-native infrastructure and high-velocity CI/CD systems. I focus on measurable reliability improvements—cutting deployment time by 50%, reducing MTTR by 40%, and maintaining 99.8% uptime across multi-tenant workloads.

I build and optimize GitLab CI/CD (primary) and Kubernetes delivery using reusable pipeline templates, smoke testing, post-deployment validation, and gated rollback strategies for safer releases. I also manage infrastructure as code with reusable Terraform IaC modules across dev, staging, and production to keep environments consistent and fast to provision.

On the operations side, I lead end-to-end incident management and author on-call runbooks, using Prometheus/Grafana and CloudWatch alerting to improve visibility and response. I bring a DevSecOps mindset by enforcing security with IAM/RBAC, AWS Secrets Manager, Trivy container scanning, and SonarQube static analysis throughout the delivery lifecycle.
