CI/CD & Security-Automatisierung
Aufbau von GitHub Actions CI/CD-Pipelines mit OIDC-Integration sowie Einsatz von Trivy, tfsec und Checkov zur automatisierten Sicherheitspruefung und Risikominimierung in Build- und Deployment-Prozessen.

Infrastructure as Code mit Terraform
Aufbau von AWS-Grundlagen mit Terraform, umfassend VPC, IAM, ALB, Route 53, ACM, S3/ECR und CloudWatch. Modularer Einsatz von Terraform fuer reproduzierbare und skalierbare Infrastruktur-Deployments.

AWS Cloud Services
Kenntnisse in AWS-Diensten wie ECS Fargate, EKS, VPC, IAM, ALB, Route 53, ACM, CloudWatch, S3 und ECR. Ausrollen von Services hinter ALB mit Health Checks, Routing und TLS-Termination.

Observability mit Prometheus & Grafana
Aufbau von Prometheus- und Grafana-Dashboards zur Ueberwachung von Cluster- und Pod-Health sowie Service-Performance-Trends. Ergaenzend Einsatz von CloudWatch fuer AWS-seitiges Monitoring.

Docker & Container-Optimierung
Einsatz von Docker fuer containerisierte Anwendungen. Reduzierung der Docker-Image-Groesse von 3,5 GB auf 75 MB (ca. 98%) durch Multi-Stage Builds.

HTTPS/TLS & DNS-Automatisierung
Automatisierung von HTTPS/TLS und DNS mit cert-manager, ExternalDNS und Route 53 fuer sichere und reproduzierbare Zertifikatsverwaltung in Kubernetes-Umgebungen.
