Senior Data & AI Platform Architect
Production AI on brownfield enterprise data
I design the data platforms enterprise AI actually runs on: dimensional and Data Vault modeling, lakehouse and warehouse architecture, streaming and batch pipelines. On top of that foundation I build the AI layer, from retrieval with source attribution to agentic workflow patterns, with the evaluation criteria and multi-tenant runtimes that keep it observable.

About Me
My strongest fit is senior hands-on work where data architecture and AI meet, combining architecture ownership with technical leadership, mentoring, and cross-team enablement. Since 2020, I have modeled and shipped enterprise data platforms in insurance, IoT, and AI-native products. Before that, my foundation was embedded systems, high-performance computing, and production software engineering.
My engineering path started early: in high school, I designed the electronic control system for a patented fire simulation device, from PCB design to Windows GUI. That full-stack mindset still guides my work today. At HDI, I modeled analytics domains against an enterprise insurance warehouse using Kimball and Data Vault 2.0 patterns. At EdgeIQ, as Senior Data Architect, I owned the tenant-facing data model for a multi-tenant IoT platform: device, event, and time-series domains, with a dbt transformation layer that kept analytics contracts stable while the underlying schema moved. The same platform ran a workflow runtime and Kubernetes provisioning controllers, so I learned early that a data model is only as good as the runtime that has to honour it. With an M.Sc. from RWTH Aachen and a background in probabilistic modeling, I build systems that handle uncertainty and hold up in production.
What sets me apart: I care about operating boundaries as much as features. Most AI projects fail on the data layer, not the model. I have spent as much time on modeling standards, lineage, and transformation contracts as on retrieval, agentic workflow patterns, evaluation criteria, and the human review boundaries that decide when a system should act and when it should ask. Teams need to understand not only what a system does, but how it fails and how to recover.
I am primarily looking for full-time senior data and AI platform roles where I can own the data platform end to end and provide hands-on technical leadership across modeling, architecture, pipelines, evaluation, infrastructure, and operational handover.
Based in Germany. German native, English fluent. Open to DACH, European, and compatible global remote roles, with consulting or advisory work as a secondary path when there is a strong technical fit.
