He came to the field through experimental particle physics and worked as a data scientist in manufacturing at thyssenkrupp before joining Deichmann.

TALK

Perfect queries, overconfident conclusions

Generative AI made it dramatically cheaper to produce a pipeline, a query, a dashboard or an analysis. It did not make it cheaper to trust the result. In a company that has been selling shoes for more than a century and, more recently, bikes and skis, source systems change constantly, a size does not mean the same thing across brands, and half the meaning of a column lives nowhere in the schema. A model writes solid SQL and Python. Syntactically the query is perfect. It cannot know what those columns means. That is the kind of thing everybody knows and nobody writes down. Notes and examples from a data organisation working through this, across pipelines, analytics, forecasting and the business acting on the numbers: what genuinely got faster, what breaks quietly, and why supplying context turns out to be the hard part, for models and for people alike.
