Node/react developer to create an APP for Shopify.

I need a Node/React developer with experience creating plugins for Shopify. The deliverable is: - A plugin that will render a given script> html code on every page of the shopify. - The plugin has a few configuration parameters such Id , color etc about 9-10 in totals, so create a configuration page where the user can type the Id, can select the color from a color picker etc once the user clicks "Save" button the plugin will render the script for those parameters. Ex. Bellow is a short example of the html code to be rendered and you need a .replace for the parameters configured. <scripst> var id = (inserthereIdfromconfig) var color = (insertHerecolorcode) <scripst> I will provide with a test shopify so that it can be tested.
