My offer to you

As a freelancer, I help teams and businesses get the most out of Kubernetes by showing them how to build an efficient and maintainable developer platform on Kubernetes that actually makes their teams' lives easier.

If you also want to build a Kubernetes platform, I can support you with the following tasks:

  • Planning of the cluster architecture, including network segmentation, ingress/egress and authorization
  • Choosing the right solution for you between different public and private clouds
  • Implementation of the basic infrastructure of the cluster using Infrastructure as Code
  • Selection and configuration of additional "out of the box" functions for your Kubernetes platform
  • Setting up the automatic rollout of features, either via existing pipelines or ArgoCD
  • Support during ongoing operations, tasks such as upgrades or complex troubleshooting
  • Provide documentation for your teams to help them easily migrate their workloads themselves
  • Coaching of teams in general topics around containerization and cloud native best practices
  • Contact me for your custom use-case!

I am also happy to help you implement an effective Infrastructure as Code (IaC) for your public cloud of choice. cloud of choice. By ensuring a high degree of automation, IaC can significantly reduce both the error rate in provisioning as well as the effort required for infrastructure changes. It is even possible to provide cost estimates before the rollout.
I am also available as a cloud native expert for adapting existing software for the cloud or Kubernetes.

Let's get started!
