I have good experience in building drupal sites from 2010. I use Drupal modules like Features, Views, CCK, Panels, Display Suite, Featured Content and Search API (and many others) to build compelling, interactive, usable websites. I have built the several kinds of drupal sites such as insurance, education, video interviewing, affiliate marketing sites. In the several projects, I have built repsonsive drupal themes and modules using drupal 6, 7, 8.
