Data & AI Engineer
Technical Lead · LLMs × RAG × Data Platforms

10 years building data and AI systems across automotive, energy, and financial services. Currently a consultant at Atos (an Eviden business), delivering AI-driven solutions for enterprise clients.

ABOUT

I turn messy enterprise data into AI systems people actually use: from RAG pipelines over financial documents to monitoring platforms on the factory floor.

Over 10 years I've moved from IoT research at Fraunhofer IEM and developer advocacy at IBM to leading an 8-person team building in-car software for a major automotive group. Today I consult for enterprise clients at Atos, combining hands-on data and AI engineering with technical leadership.
