What I Do

The pattern repeats in almost every conversation. A GenAI prototype exists, it works, and somebody has now promised it to the wider business. What follows is not a modelling problem — it is an infrastructure problem. Where does inference run. Who pays for the GPUs when nobody is using them. What happens to the data. Who signs it off.

That is the work below. Six areas, all of them things I have had to solve rather than read about, and all of them available separately — most engagements start with one of them, not the whole list.

  • 01

    LLM Serving on Kubernetes

    Production-ready self-hosted LLM serving with vLLM, LiteLLM and Helm charts on Kubernetes — including AI gateway, multi-model routing, token quotas and API-key management. For Java/Spring enterprises across Frankfurt am Main, Mainz, Koblenz, Limburg an der Lahn, Hessen — and remote across Germany.

  • 02

    GPU Scheduling & Cost Engineering

    NVIDIA GPU Operator, MIG partitioning and Karpenter with GPU nodes on Kubernetes (AWS EKS, GKE). Spot-GPU strategies, right-sizing and multi-tenancy — making GenAI workloads affordable. Consulting for companies in Frankfurt, Mainz, Koblenz and all of Germany.

  • 03

    RAG Infrastructure (Qdrant, Embeddings, Rerankers)

    Production RAG on Kubernetes with Qdrant, embedding pipelines and reranker models — GDPR-compliant and air-gapped-capable. For regulated industries (banking, insurance, pharma) in Hessen, Rheinland-Pfalz and Germany-wide.

  • 04

    AI Observability & FinOps

    Prometheus + Grafana for GPU and token metrics, Langfuse for tracing, cost tracking per tenant and per model. "What does a token cost?" — finally measurable. Consulting around Frankfurt am Main, Mainz, Koblenz and remote Germany-wide.

  • 05

    EU AI Act & GDPR Compliance

    Compliance advisory for self-hosted LLMs: EU AI Act risk classification, GDPR-compliant data flows, air-gapped setups and audit logging. Specialized for German enterprises in regulated industries — insurance, banking, pharma, public sector.

  • 06

    GenAI Integration in Java/Spring (Spring AI)

    Spring AI, Spring Boot integration of custom LLM gateways, GenAI building blocks for existing Java enterprise applications. The rare combination of Cloud-Native, Enterprise Java and compliance — for customers in the Rhine-Main area (Frankfurt am Main, Mainz, Wiesbaden, Hessen) and all of Germany.

Who this is not for

If you are looking for someone to fine-tune or train models, this is the wrong desk — I operate models, I do not build them. The same goes for pure data science work, and for teams that want a proof of concept to show a board next month with no intention of running it afterwards. Those projects can be done, they are just done better by somebody else.

Where this does fit: you already run software in production, you have a real workload in mind, and the constraint you keep hitting is infrastructure, cost or compliance rather than the model itself.

How an engagement usually runs

Almost always with a short assessment — two to three days spent on what you run today, where the AI workload has to sit, and what your compliance situation genuinely demands rather than what a vendor deck claims. The output is a written recommendation with an architecture sketch and a cost estimate, and it is yours to act on with or without me.

Implementation after that is scoped in blocks of a few weeks with something working at the end of each — a running cluster, a serving stack, a documented data flow. Not an open-ended retainer. Everything is handed over with the Helm charts, the Terraform and the write-up, because the point is that your team can run it once I am no longer around.

Frequently asked

What does a typical engagement look like?

Usually a short assessment first — two to three days looking at what you run today, where the AI workload is supposed to sit, and what your compliance situation actually requires. That produces a written recommendation you can act on with or without me. Implementation work after that is scoped in blocks of a few weeks rather than open-ended retainers.

Do you work remotely across Germany?

Yes. Based in Limburg an der Lahn, I work on-site across Frankfurt am Main, Wiesbaden, Mainz and Koblenz, and remotely with companies anywhere in Germany. On-site tends to matter most at the start of a project and during handover; the rest works well remote.

Can you self-host LLMs in a GDPR-compliant, EU AI Act-aware way?

Yes. That is the core of the work: self-hosted LLM serving with vLLM and LiteLLM on Kubernetes, air-gapped-capable RAG, EU AI Act risk classification, documented data flows and audit logging. Nothing leaves your infrastructure unless you decide it should.

Do you also do plain Kubernetes and cloud work, without any AI?

Yes, and a good share of the work still is exactly that. Cluster setup, Helm, Terraform, CI/CD pipelines and cost work stand on their own. The AI specialisation sits on top of that foundation rather than replacing it.

Which platforms and tools do you specialise in?

Kubernetes on EKS and GKE, AWS, NVIDIA GPU Operator, Karpenter, vLLM, LiteLLM, Qdrant, Terraform and Helm — with observability through Prometheus, Grafana and Langfuse. On the application side: Java, Spring Boot and Spring AI.

Do you integrate GenAI into existing Java and Spring applications?

Yes. Most German enterprises are not going to rewrite a working Spring estate to adopt GenAI, and they should not have to. I integrate LLM gateways and GenAI building blocks into what already runs, using Spring AI and Spring Boot.
