Freelance · Cloud & Platform Engineering

Hi, I'm Hauke. I build platforms
that run themselves.

I help teams design, automate and operate cloud-native infrastructure – from bare-metal Kubernetes to fully GitOps-driven platforms – so developers can ship instead of firefighting.

Start a project See my open-source work

Services

Hands-on engineering and consulting, remote or on-site.

Kubernetes platforms

Design and build of production clusters on bare metal, private or public cloud – networking, ingress, storage, upgrades and day-2 operations.

GitOps & CI/CD

Flux-based delivery, Helm chart engineering, reusable pipelines for GitHub and GitLab, and release automation with semantic versioning.

Infrastructure as code

Terraform/OpenTofu modules, Packer golden images and Ansible automation – reproducible environments across Hetzner, AWS, Azure and OpenStack.

Identity & security

Single sign-on with Keycloak/OIDC, hardened defaults, secret management and least-privilege access for people and pipelines.

Observability

Metrics, logs and alerting that tell you something useful – plus custom exporters when off-the-shelf ones fall short.

Go tooling & AI integration

Kubernetes operators, APIs and CLI tools in Go, and pragmatic integration of self-hosted LLMs into engineering workflows.

How I work

Small steps, visible progress, and a platform your team can own afterwards.

Understand

We look at your goals, constraints and the current setup together.

Design

A clear, documented target architecture – no lock-in, no magic.

Build

Everything as code, reviewed in Git, delivered in iterations.

Hand over

Documentation, pairing and enablement so your team stays in control.
