Most GenAI pilots die on the way to production: retrieval nobody measured, prompts nobody evaluated, compliance nobody scoped. I build the systems that survive that trip, and the harnesses that prove they work. AI Engineer at NFON AG, M.Sc. AI candidate, Google Cloud Professional Data Engineer.
An evaluation harness that scores RAG pipelines and agents straight from their OpenTelemetry traces: retrieval metrics, trajectory evaluation, LLM-as-judge with a calibration module that checks the judge against human labels, and a paired-bootstrap CI gate that blocks only statistically significant regressions. The benchmark is fully reproducible: committed traces and a judge cache re-score without an API key.
Production RAG on Terraform-provisioned Azure: dense vector search over Azure AI Search plus cross-encoder reranking, served through FastAPI microservices with GDPR-compliant data handling.
Provider-agnostic research agent on a custom MCP server over a mock CRM, with a code-enforced guardrail that every claim traces back to a real tool result. Claude and OpenAI swap behind one protocol.
Answers natural-language questions about any public repository. Pydantic AI with ten focused tools over the GitHub REST API that the model chains itself, so you can ask it things like “which open issues look stale?”
One week, fixed scope, fixed price. I review the system you have and tell you exactly what stands between it and production: architecture, retrieval quality, evaluation, and the GDPR and EU AI Act gaps that surface late and cost the most.
You leave with a report you can act on with or without me. Built for German Mittelstand teams and the agencies delivering for them.
Enquire about the auditReranking looked like an obvious win. I built a calibrated eval harness around it, with the judge checked against human labels and a paired bootstrap on the deltas, and that is how I found out how much of the win was real.
Tell me where it broke. Thirty minutes, no pitch. If the audit isn't the right first step, I'll say so. Ingolstadt, Germany; remote across the EU.
