A leading boutique commercial real estate firm in the USA needed a platform to visualize their portfolio properties. Their previous database listed over 5,000 properties, but filtering them by location, zoning laws, and size was slow and frustrating for their brokers.
I designed and built LocatePro, an interactive map tool that helps users search and filter commercial properties easily.
The Challenge
Brokers were losing leads because property searches were slow:
- Slow Mapping: The browser would crash or freeze when rendering thousands of pinpoints at once.
- Clunky Filtering: Users had to fill in long forms and click submit, waiting for a full page refresh on every search.
- Layout Shift: On mobile screens, the map dimensions shifted constantly, blocking usability.
The Solution
I engineered a performant frontend and custom Leaflet API wrapper:
- Map Rendering Optimization: Implemented canvas marker clustering to cluster thousands of properties into clean nodes. This prevents browser thread blocking and allowed the map to render instantly.
- Fluid Real-time Filtering: Programmed client-side state filters. When a user checks a zoning filter or changes a size slider, properties update instantly on the map without loading latency.
- Responsive Design System: Designed a split-pane layout (map on one side, clean list cards on the other) using CSS Flexbox. It shifts to a tabbed map/list view on mobile screens.
"Our brokers can now locate commercial listings for clients on their phones in seconds. LocatePro changed how we do deals."
The Results
The new website gave immediate benefits to the client:
- 3x faster property finding times for brokers.
- 100% database accuracy synced with real-time property details.
- Zero browser freezing, even when displaying thousands of listings simultaneously.
