Biography

Tomás owns the path an event takes from your product to a dashboard. That is ingestion, storage, the query planner, and the part where all of it has to stay under two hundred milliseconds while someone drags a date range around.

He writes about the engineering side of measurement: schema drift, late-arriving events, idempotency, and why most real-time analytics is neither.
