About Me

Geek Cell is a specialized AWS Cloud & Platform Engineering consultancy founded by Christian Kappen — a Senior Cloud Architect with 26+ years of engineering experience and deep expertise in building production-grade AWS infrastructure from the ground up.

I help startups, scale-ups, and enterprises design, build, and operate secure, highly available AWS environments. My work spans multi-account architectures, Kubernetes platforms, Infrastructure as Code, and end-to-end cloud migrations — always with a focus on security, compliance, and operational excellence.

What I Do

  • AWS Cloud Architecture — Multi-account strategies, Landing Zones, Well-Architected reviews, and production-grade infrastructure design
  • Kubernetes & Container Platforms — EKS and ECS clusters, Helm, ArgoCD, and GitOps-driven delivery
  • Infrastructure as Code — Terraform, Terragrunt, and OpenTofu at scale across dozens of AWS accounts
  • Cloud Migrations — Full migrations from on-premise or other cloud providers to AWS
  • Security & Compliance — IAM architecture, encryption (KMS), network segmentation, GDPR, ISO 27001, SOC 2, and BSI compliance
  • CI/CD & DevOps — GitHub Actions, GitLab CI, blue-green deployments, and automated pipelines
