I've been mostly working with Drupal since quite few years as CMS. Other than Drupal I've also worked with Wordpress, Ionic, AngularJS, etc. In Drupal, some of my key strengths are understanding of Drupal core. I have used quite a few of contributed modules and customized them from time to time. I've also written custom modules while working on different projects, few of them are Flag Cool Note and Commerce Attributes Date which are successfully contributed and maintained on Drupal.org. I also submit patches for contributed modules on Drupal.org.
