• Configure identity brokering rules, realm roles, client scopes, and token exchange policies within Keycloak to power secure authentication for React and Spring Boot services
• Design, build, and maintain end-to-end CI/CD pipelines for automated image builds, vulnerability scanning, automated testing gates, and zero-downtime rolling deployments via Helm
• Implement robust platform security controls, including Kubernetes Ingress controllers (NGINX/Traefik), TLS certificate automation (cert-manager), network policies, and container image scanning (Trivy)
• Automate secrets management and configuration injection across environments using tools such as HashiCorp Vault, AWS Secrets Manager, or Kubernetes External Secrets Operator
• Provision, monitor, and maintain supporting backing infrastructure including managed PostgreSQL instances and secure Amazon S3 storage buckets
