I understand that you are looking for someone to modify the free Shopify theme so that it works properly. Specifically, you would like me to modify the option to "hide other variant media while a variant is selected" so that it does not display other variant media when a variant is selected.
With my experience in full stack development and extensive knowledge of ReactJS, NodeJS, Vue.js, AngularJS, TypeScript, HTML5 & CSS3, Sass/SCSS preprocessor languages, PHP, and more, I am confident that I can deliver an excellent result. My skillset includes frontend and backend web development with ReactJS, NodeJS, Vue.js, AngularJS, TypeScript, HTML5 & CSS3 as well as Laravel & Django. This makes me well-versed in adapting to new technologies as needed.
I would be more than happy to discuss this project further if needed and look forward to working together on this opportunity!
