INTERNAL_BUILD // PUBLIC RECORDS, MADE USABLE
Oro Property Datamart
Pierce County publishes its assessor and treasurer rolls as raw weekly file drops — public data that is practically inaccessible. Oro downloads, validates, and loads all of it into one queryable database on our own hardware, every week, unattended: 342,000 appraisal accounts, 642,900 recorded sales, structures, land, and tax rolls — every parcel in the county. Any parcel's valuation, structure, and sale chain answers in milliseconds. Aggregate analytics and per-parcel answers — never lists of people. The pattern — ingest, validate, serve — runs the same on any data your business already has.
