Developed and programed a system to automatically pull/update infomation on over 60,000 items (homes, land, condos, etc....) continuously from multiple IDX's/RETS/MLS Servers (Internet Data Exchange for Real Estate data/listings). This included automatic and accurate geocoding with Street address correction. Plus Storage of Millions of Photos from all items. We also built a map search engine that can display items on top of Google Maps with clustering and with the ability to search and sort items by multiple means, (price, size, address/location). Plus built the accompanying API and database systems. We also host and maintain it.
The interface is fully responsive and displays around 200 items on the map, more then similar sites.
