Automating infrastructure
that scales, deploys,
and never breaks
under pressure.

4+ years running Kubernetes (EKS / RHOCP 4.x), GitOps CI/CD, HashiCorp Vault & Istio mTLS for banking and media at TCSCIBC and Tata Play. Every number on this page is from production, not a template.

CI/CD Pipeline, end-to-end.

Every commit travels through seven gated stages — from PR validation to production canary — with Snyk vulnerability scanning, SonarQube quality gates, and HashiCorp Vault dynamic secret injection at each environment.

I'm the engineer you call at 2 a.m. when production is down — and the one who makes sure you never need that call again. — Sreeharinath Peetla · The 2 a.m. Engineer

Istio Traffic Mirroring & Canary Deployments

Mirrored live traffic for zero-risk prod testing — MTTD ↓40%, MTTR ↓35%, mTLS locked on every service pair.

✗ Before
  • Big-bang releases — 100% traffic switches at once
  • No production traffic testing before go-live
  • Plaintext service-to-service traffic
✓ After
  • Mirrored live traffic for zero-risk prod testing
  • Canary rollouts — 10% → 50% → 100% gradually
  • mTLS locked on every service pair

HashiCorp Vault Enterprise Secrets Platform

Every secret short-lived and auto-rotated — 0 hardcoded credentials left in CI/CD or Kubernetes.

✗ Before
  • Plaintext Kubernetes Secrets committed in YAML
  • Hardcoded credentials in CI variables
  • Static database passwords — never rotated
✓ After
  • KV v2 engine + dynamic database secrets
  • AppRole & Kubernetes auth for pipelines and pods
  • Short-lived credentials, auto-rotated on schedule

30→5min per deploy

CI/CD Automation with Shift-Left Security

Deployment time cut from 30 min to 5 min — Snyk + SonarQube + Trivy gates eliminated manual release errors.

✗ Before
  • Manual multi-step deploys — slow, error-prone
  • Vulnerabilities caught late — in production
  • No quality gate between commit and release
✓ After
  • 7 gated stages from PR validation to prod
  • Snyk + SonarQube + Trivy scan every PR
  • One-click image promotion via JFrog Artifactory

RHOCP 4.x High-Availability Microservices Platform

Multi-stage Helm promotion across DEV → PROD — 15+ microservices with instant rollback and zero-downtime deploys.

✗ Before
  • Tribal-knowledge deploys, no rollback path
  • Environment drift — dev ≠ staging ≠ prod
  • 15+ devs pushing to one shared release branch
✓ After
  • Helm multi-stage promotion with env values
  • Versioned charts + instant rollback strategy
  • Git branching strategy + runbooks in Confluence

Prometheus + Grafana + Fluentd Observability Stack

Proactive alerts fire before users notice — 10+ outages averted, logs and metrics finally correlated in one place.

✗ Before
  • Reactive firefighting — alerts after users complain
  • Logs and metrics trapped in separate silos
  • Slow incident detection and diagnosis
✓ After
  • Prometheus + Grafana dashboards with SLOs
  • Fluentd DaemonSet → Kibana log-metric correlation

Terraform AWS EKS Infrastructure & Autoscaling

Slashed the AWS bill 30% with Terraform IaC + Lambda off-hours scheduling — 20+ services autoscaled through peak DTH traffic.

✗ Before
  • Manual AWS console provisioning — slow, drift-prone
  • Idle EC2 running 24/7 at full cost
  • Over-provisioned capacity for peak traffic
✓ After
  • Terraform IaC — EKS, VPC, EBS from modules
  • Lambda scheduler shuts non-prod off-hours
  • HPA + Cluster Autoscaler scale on real load
