DevOps and SRE Engineer, Kubernetes, GitOps, Observability

Hey, I'm Subodh, based in Mumbai.

I'm a DevOps and SRE engineer. I spend my time building and breaking infrastructure: Kubernetes clusters, GitOps pipelines, CI/CD, and observability stacks. I've run production Kubernetes for an e-commerce platform serving over a million users a month and for a healthcare AI platform.

This blog is where I write up things I figured out the hard way: config quirks, debugging sessions, homelab experiments, the occasional opinion. No tutorials copied from docs. Mostly things I wish existed when I was searching at 2am.

What I do

☸️ Kubernetes at scale

Managed clusters on GKE and EKS for platforms running dozens of microservices, deployed with Helm.

🔁 GitOps delivery

ArgoCD with automated self-healing across 30+ microservices, plus Jenkins, GitLab CI and GitHub Actions pipelines.

🏗️ Infrastructure as code

Terraform for AWS (EKS, RDS), Ansible for configuring fleets of servers.

🔭 Observability and SLOs

Prometheus, Grafana and SLO/SLI thinking, so problems show up before users notice.

🛡️ DevSecOps

SonarQube, OWASP ZAP and Trivy in the pipeline, with least-privilege IAM and Velero disaster recovery.

🧩 Web and CMS

Frontends in React, Next.js and Astro, with Strapi as a headless CMS behind them.

Learning and exploring

🤖 MLOps with Kubeflow

Taking ML workloads from notebooks to reliable pipelines on Kubernetes.

🚪 Gateway API and Envoy

Modern traffic routing for clusters, using Envoy Gateway in my own lab.

📡 OpenTelemetry

Vendor-neutral traces, metrics and logs, instead of one tool per signal.

🔐 Supply chain security

Scanning images and dependencies early, so problems are caught before they reach production.

Homelab

I run two separate setups. One is deliberately tiny, the other is a real cluster.
