Data platform engineer — twenty years across banking, telco, automotive and insurance, mostly in the contracts-driven middle (ingestion, lineage, governance) rather than the modelling.

Now running Cordata, a small consultancy in Budapest working with DACH mid-market clients. I write up the things that went wrong at cordata.tech/en/blog — currently Rust, OpenTelemetry, and why observability code is the one part of a system that nothing else is watching.
