Proof of Experience

Senior DevOps Engineer

Ericsson Global India Pvt. Ltd. · Jun 2025 – Present

  • Led platform engineering across 10+ person cross-functional team — infrastructure automation, security-first CI/CD, and self-healing systems for enterprise telecom platform.
  • Built production 3-tier AWS infrastructure (VPC, 3 AZs, CloudFront + WAF + ALB, EC2 ASG, Aurora Multi-AZ, ElastiCache) with Terraform modules - handles 5,000 req/s, auto-scales 3→20 instances, <30s DB failover
  • Implemented IaC security scanning (tfsec + Checkov + OPA) in CI zero misconfigurations reach production; Infracost shows cost impact on every PR
  • Operated K8s across 3 environments (self-managed, EKS, OpenShift) serving 15+ production microservices with standardised Helm chart deployments and environment-specific value overrides
  • Karpenter autoscaling with Spot optimisation 60-70% node cost reduction; bin-packing consolidation eliminates half-empty nodes
  • Designed 18-stage DevSecOps pipeline (Jenkins + ArgoCD + Argo Rollouts) with 6 security layers: secret scan → SCA → SAST → Trivy image scan → Cosign signing → DAST (OWASP ZAP) blast radius reduced 100% → 5%
  • Supply chain security: Cosign + Kyverno admission control - only signed, scanned images from ECR run in production (SOC2 passed first attempt)
  • Enforced CIS/NIST-aligned policies: Pod Security Standards (restricted), NetworkPolicies (default-deny), mTLS (Istio), RBAC least-privilege; secrets via AWS Secrets Manager + KMS
  • Deployed Prometheus + Grafana + AlertManager + EFK with ServiceMonitor auto-discovery; structured alerting (P1→PagerDuty, P2→Slack, P3→Jira)
  • Istio service mesh + Jaeger distributed tracing across 15 microservices MTTR reduced from 2+ hours to <5 minutes.

  • End-to-end ownership of cloud infrastructure, platform architecture, and DevOps toolchain across AWS for enterprise-scale product delivery teams.
  • Architected 15-account AWS Landing Zone (5 OUs) with Terraform: SCPs, IAM Identity Center SSO, OIDC federation for CI/CD — account provisioning reduced from 2 weeks → 30 minutes
  • Centralised security: GuardDuty + Security Hub + AWS Config + CloudTrail across all accounts; immutable log archive; SOC2/ISO27001 compliant
  • Designed multi-region active-passive DR (Route53 health-check failover + Aurora Global Database + S3 CRR) — measured RTO: 3 minutes, RPO: <1 second; quarterly drills with AWS FIS chaos experiments
  • Built serverless security remediation engine (EventBridge + SQS + Lambda + DynamoDB + SNS) — auto-fixes AWS Config violations in 90 seconds; full DynamoDB audit trail; API Gateway compliance dashboard
  • Reduced AWS spend 35% ($180K/year): non-prod auto-stop (Lambda + EventBridge), Karpenter consolidation, VPA rightsizing, VPC Endpoints, Savings Plans, GP2→GP3, S3 lifecycle policies
  • Kubecost per-namespace chargeback; mandatory tagging via SCPs; Cost Explorer + Compute Optimizer + AWS Budgets governance
  • Built reusable Terraform module library (VPC, EKS, RDS, IAM, ALB) for multi-region, multi-account deployments — CI/CD-driven plan/apply with separate state per account; drift detection via scheduled plans
  • Built enterprise OS patching automation (18-step lifecycle, 7-dimension validation, auto-rollback) on Ansible Automation Platform — 500+ RHEL servers/month, zero downtime, full ServiceNow ITIL CR lifecycle
  • 12 production-grade idempotent Ansible roles; multi-system monitoring silence (Alertmanager + CloudWatch + PagerDuty) with auto-expire; AES-256 Vault for all credentials.
