Aryman Rawat

I’m a DevOps Engineer focused on building scalable, secure AWS infrastructure for fintech trading and latency-sensitive systems. I bring hands-on expertise across Kubernetes (EKS), GitOps with ArgoCD/Helm, and IaC with Terragrunt + OpenTofu/Terraform to deliver reliable platform automation.

At Paytm Money, I designed and provisioned a self-hosted Bitbucket Runner fleet on EKS using OIDC-based IAM federation, eliminating static credentials across CI workflows. I also deployed and operated ArgoCD, Argo Rollouts, and ArgoCD Image Updater to enable automated GitOps deployments across 25+ microservices with stage auto-sync and production manual-gate controls.

I’ve authored a reusable Terraform module library (14+ modules) and built CI for the IaC repository with smart change detection (plan/apply only on diffed modules) and per-environment IAM role routing. Beyond CI/CD, I’ve owned production infrastructure improvements—auto-scaling and right-sizing reduced EC2 runtime by 50%—and delivered zero-downtime migrations for Redis and Elasticsearch with zero data loss, plus Qualys-driven patch automation and 100% audit compliance.
