Mat Swinianski
Data & Analytics Consultant. I build data platforms end to end, from the event landing in the cloud to the number someone makes a decision with. One person, the whole path. No handoffs.
I’ve sat in the meetings where the dashboard gets used, so I don’t build pipelines for their own sake. Deel, Deliveroo, AirHelp, Convex.
Most AI projects stall in the same place: the data underneath isn’t trustworthy enough to act on. That layer is the one I build.
