What I Do

Senior DevOps & Platform Engineer with 10+ years building, scaling, and automating cloud-native platforms across AWS, GCP, and Azure. I design and operate large-scale Kubernetes platforms, build reusable infrastructure as code, and make software delivery fast, observable, and secure.

I've architected and operated production platforms for financial institutions, telcos, airlines, and fintechs — including a Platform-as-a-Service on AWS EKS hosting trading, clearing, and market-data workloads at a commodity futures exchange and clearinghouse.

Across India, Germany, and Singapore, my work spans Kubernetes (EKS/GKE), Terraform, CI/CD, multi-cloud networking, observability, and DevSecOps.

How I Do It

I lean on disciplined engineering: infrastructure as code with Terraform, GitOps with ArgoCD, declarative observability, and automation that removes toil. I've led an observability migration from Prometheus + Thanos + Tempo to the Elastic Stack, cut cloud spend by ~35% through automation, and reduced environment setup time by ~40% with reusable Terraform modules.

As a CNCF Kubestronaut (CKA, CKAD, CKS, KCNA, KCSA), I care deeply about running Kubernetes securely and reliably in regulated, financial-grade environments — from network firewalls and segmentation to secrets management and CIS benchmarks.

Areas of Focus

Where I spend my time — the practices and platforms I build teams and systems around.

Kubernetes & Platform

Architecting and operating large-scale PaaS on AWS EKS and GKE — multi-environment clusters, Helm charts, PDBs, node group scaling, secure workload access, and production-grade day-2 operations.

Infrastructure as Code

Reusable Terraform modules for AWS/GitHub provisioning, declarative alerting, secrets/KMS/ACM automation. Cut environment setup time ~40% and improved consistency across environments.

Cloud Networking & Security

VPC design, Transit Gateway, Network Firewall, PrivateLink endpoint services, per-ISV security group segmentation, WAF, and VPN-only enforcement across multi-account AWS environments.

Observability

Prometheus, Grafana, Loki, Thanos, Tempo, and the Elastic Stack. Led migration to Elastic Cloud with alerting managed declaratively in Terraform; built monitoring stacks for VPN and connectivity.

CI/CD & GitOps

GitHub Actions, ArgoCD, Jenkins, GitLab CI. Self-hosted runners on EKS with Terraform + Helm, golden pipelines, and secure multi-account delivery.

DevSecOps & Cost

CIS benchmarks, image scanning, Vault/External Secrets, EKS Pod Identity/IRSA, VAPT remediation, and cloud-cost optimization automation reducing spend by ~35%.
