Key Strengths

  • Led production incident response and rollback using GitOps (Argo CD sync history) for EKS cascading failures
  • Designed and ran quarterly DR failover exercises simulating primary AWS region loss (Route 53 DNS failover, RDS promotion validation)
  • On-call outage recovery from CloudFormation misconfiguration; restored service via manual ALB then rebuilt stack from version-controlled templates
  • Built secure CI/CD pipelines with automated testing and security gates (SonarQube, Checkmarx, Snyk, Trivy) deploying to Kubernetes
  • Diagnosed CI/CD quality-gate false passes due to expired SonarQube token; implemented explicit failure validation and token rotation
  • Implemented multi-environment Terraform platform with modular design, remote state/locking, peer-reviewed promotion, and automated drift detection
  • Established infrastructure change controls with mandatory plan/approve gates in GitLab CI to prevent unsafe applies
