About This Project

Built a comprehensive real estate platform for a property firm managing rental and sale listings across multiple cities. Features include interactive map-based property search (Google Maps API with custom clustering), advanced filters (price, area, bedrooms, amenities), virtual tour embed (Matterport integration), mortgage/EMI calculator, saved searches with email alerts, and a complete agent CRM for lead tracking and follow-ups. The backend uses PostGIS for spatial queries, enabling sub-200ms search results even with 3,000+ active listings. The platform also includes a property comparison tool and automated listing syndication to third-party portals.

Challenge

Implementing performant map-based search with thousands of property markers and complex polygon-based location filters while keeping the UI smooth on mobile devices.

Solution

Used PostGIS spatial indexing for server-side geo-queries, implemented marker clustering with Supercluster for client-side rendering, viewport-based lazy loading of markers, and debounced search-as-you-pan with Redis caching of frequent search areas.
