Critical systems. Under your control.

One engineer from architecture to operations. I design infrastructure, platforms, and production AI for business-critical systems, build them with your team, and stay until they run without me.

Most engagements start when

  1. A new platform is moving from design into delivery.

  2. Cost, control, or regulation is changing where systems run.

  3. Platform changes have become slow or risky.

  4. AI has to move from prototype to production.

Capabilities

What I build.

Infrastructure

Workloads run where cost, control, and regulation make sense for the business, with the trade-off written down.

Typical work
  • Placement across bare metal, hyperscaler, or sovereign cloud
  • Compute, GPU, network, and storage delivered as code
  • Portable foundations with explicit exit paths

Platform

Changes ship faster without making the platform harder to operate after go-live.

Typical work
  • Kubernetes delivered as code across environments
  • GitOps and CI/CD with auditable, reversible changes
  • SLOs, alerting, and runbooks agreed before handover

Production AI

AI workloads reach production under your data rules, on infrastructure you control.

Typical work
  • Self-hosted LLM and speech inference on your GPUs
  • Retrieval and agent systems built for evaluation and cost
  • OpenAI-compatible endpoints, no single model provider

Regulated environments

Security zones, classification levels, and audit evidence as design inputs, not a pre-launch retrofit.

Typical work
  • BSI IT-Grundschutz and protection-requirement analysis
  • Air-gapped and zoned networks
  • Controlled exchange across security boundaries
