/ The problem

Every multi-market operator hits the same wall: two MLSs describe the same field three different ways, addresses never match, and a feed goes stale on a Friday without anyone noticing until Monday. Every downstream product inherits that mess.

/ Architecture

5 stages, each one observable and individually replaceable.

  1. 01Replicate

    Incremental RESO Web API sync with change tracking, backfill, and per-MLS rate limiting.

  2. 02Normalize

    Field mapping to a canonical schema; property types, statuses, and units reconciled across sources.

  3. 03Resolve

    Address standardization and entity resolution so a listing, a parcel, and a CRM record become one property.

  4. 04Enrich

    Parcel, permit, demographic, and transaction history joined onto the canonical property record.

  5. 05Serve

    Read APIs, a warehouse schema, and vector indexes for retrieval — all from one lineage-tracked source.

What people actually use

  • Internal search and property lookup
  • Analytics warehouse tables with documented lineage
  • Retrieval index powering downstream AI features
  • Feed health dashboard with staleness alerting

How we know it works

  • Feed freshness and sync lag per MLS
  • Entity resolution precision on a labeled sample
  • Schema drift incidents caught before downstream impact
  • Query latency at the serving layer

Baselines are captured during discovery so the effect of the system is measurable against the process it replaced — not asserted afterward.
