Apex Realty had a legacy IDX listing platform that took up to 6 hours to sync new property listings, resulting in outdated data and lost buyer inquiries. Their search maps were also slow and unresponsive on mobile devices.
We engineered a custom Next.js frontend with an optimized serverless backend API that connects to the RESO Web API. We implemented a cron job syncing properties every 15 minutes, using Redis for instant caching of listing payloads. We also integrated Mapbox GL JS with clustering for property visualizations.
Listing synchronization times were reduced from 6 hours to less than 12 minutes. The mobile conversion rate increased by 45% because property detail pages loaded under 350ms, earning perfect 100/100 Core Web Vitals marks.
