An enterprise distributed property pipeline ingesting millions of daily MLS & CREA DDF listings across North America, serving public search traffic for a major regional portal. I worked on the platform for eight years, and it is still in production today.
Multi-tier delta ingestion — scheduled polling and webhooks feed a Redis buffer queue that shaves traffic peaks before anything reaches the database.
MySQL master for ACID writes, a read-replica cluster for query fan-out, and a sub-millisecond Redis cache tier in front of the hottest listings and geographies.
Broke a long-lived monolith into Listing, Price History and Lead services, delivered through an API gateway and CDN.
