Callum Reid
Data Engineer
Callum is the person who makes "schema-less" actually work. He maintains the inference layer that turns messy event streams into clean, queryable structure. Before Vireo he ran the analytics stack at a retailer that had fourteen dashboards for the same number. He has strong opinions about naming things, most of which he'll share unprompted. He lives a ten-minute walk from the studio, which is convenient for both of them.
