With over half a decade of web development experience, predominantly in Shopify and WordPress, I am confident I can design and develop the API-driven WordPress plugin your project necessitates. My resume is marked by an extensive proficiency in RESTful APIs, JSON, PHP, HTML5, CSS3, SASS, Bootstrap, Google API, jQuery and JavaScript - all practical skills pivotal in creating the plugin that will pull data from your CRM to your WordPress site.
I have a deep familiarity with API integration having successfully worked on projects involving connecting various platforms such as Amazon, eBay, and Ali Baba. This demonstrates my understanding of the ins and outs of API requirements. Moreover, my strong understanding of CSS and UI design combined with bootstrap grid enables me to create pages that are 100% responsive and compatible with multiple themes - something you specifically emphasize in your project description.
