I build systems that stay calm
when traffic gets loud.

I’m Shivam Kumar — a Platform & SRE engineer. I turn chaotic distributed systems into predictable, observable, and cost-aware platforms.

Flink on Kubernetes Platform

A self-serve streaming platform with guardrails: sane defaults, paved paths, and operational clarity for developers.

  • Lag-aware autoscaling + self-healing job orchestration
  • Multi-tenant isolation and upgrade-safe deployments
  • Opinionated observability: SLOs, golden signals, runbooks

Cost-First Metrics Migration

Re-architected metrics storage and query patterns to reduce spend without sacrificing incident-time fidelity.

  • Prometheus → VictoriaMetrics migration with rollout playbook
  • Dropped cardinality hotspots via re-labeling + guidelines
  • Cut infra costs by ~60% while improving query latency

GitOps Delivery System

A delivery pipeline that makes shipping boring: previews, policy checks, and safe progressive rollouts.

  • ArgoCD-based sync strategy + standardized app templates
  • Guardrails: policy-as-code, secrets hygiene, drift detection
  • Reduced operational toil by ~50% through automation

Experience

I like roles where the job isn’t “keep it up”, it’s “make it resilient.”

The Scale Up

Built an in-house Flink on Kubernetes platform: self-healing, lag-aware scaling, and clear on-call ergonomics.

The Cost Killers

Migrated Prometheus → VictoriaMetrics, reducing infra spend by ~60%.

Automation Wins

Built platforms + GitOps pipelines, cutting operational toil by half.

Ingram Micro

Software Engineer — SRE
Jan 2019 — Nov 2020

Foundation years: multi-stage CI/CD on AWS & Azure, lift-and-shift migrations, and making “secure by default” non-negotiable.

Writing

I write to turn tribal knowledge into repeatable playbooks. Expect posts about Kubernetes, Terraform, platform patterns, and reliability thinking.
