Shopify Developer with Excellent JavaScript

I'm looking for a web developer with experience working with Shopify themes and development. The client is a boutique ecommerce store that needs theme updates – primarily the work will involve Shopify liquid templates and frontend development, including AJAX and cart behaviors, although some work will need to be done to incorporate Shopify CMS components for content management on the site as well. It is critical that you've worked with Shopify before (specifically working with products / variants, Add to Cart behavior), as well as have experience working with SASS, Gulp, and Browserify / CommonJS, as the theme incorporates all of these technologies. Required skills: - Code versioning using Git (GitHub) - Shopify development experience, as well as general ecommerce knowledge - JavaScript & CommonJS fluency - SASS / SCSS expertise - HTML / Liquid template expertise
