What this diagram shows

  • Listings are moderated before they go live
  • Search runs on a dedicated search index with geo queries
  • Enquiries become leads routed to the owner or broker

Prompt used

A property listing platform: owners and brokers post listings through a web app, buyers and tenants search on web and mobile. Services: listing service with moderation, media service storing photos in object storage behind a CDN, search service on Elasticsearch with geo search, lead service capturing enquiries, and a visit scheduling service. Maps come from an external maps API; leads are pushed to broker CRMs.
