Homer is a portal with advertisements for Real Estate with innovative architecture. The engine was written with PHP for elastic search and tag functions using inner metalanguage. It can define different kinds of ads and integrate them via API with all types of programming environments. The system was designed to easily allow all other programs with similar ads to enter properly formatted files into it.
Homer is a perfect example of an individual script integrated with Drupal. The interface of the portal is 100% Drupal, but the ad engine (called x100) was written from scratch by us and linked with Drupal by a specially designed module we have created as well.
The whole system was constructed with efficiency in mind to smoothly operate hundreds of thousands of enteries using most standard servers. It was a complete success.
