For a new software as a service venture I helped develop an application that dealt with filtering large amounts of real estate related data using advanced filters.
Like how amazon drills down products but a much bigger dataset. There was a good amount of time learning how to communicate with the Elastic Search Engine. This allowed us to do advanced things on real estate addresses such as geofencing.

• Created a web service that communicated with an Elastic Search Engine server.
• Web service pulled back data via SOAP and XML for final consumption by an ajax endpoint.
• Filters could be applied one by one to the end query quickly and easily.
• Safeguards against selecting too much data (performance issues) had to be dealt with.
