Sure! Can you please share that Existing Template along with the required Customization?
I am just new here but I have been working since 6+ years in this industry but I have 4+ years of experience in Shopify Store Design & Development with the Front-End & Back-End Development Skills. I'm well educated about what customization can be possible & what can't.
*My Skills-*
> Configuring & Customize ready-made Shopify Themes
> Shopify Apps Development & Customization
> 3rd party Shopify App/API integration like social networks, CRM & others.
> Hand-coded HTML, accessible, validated, semantic and SEO-friendly.
> Cross Browser Compatibility (IE, FireFox, Chrome, Opera, UC & Safari).
I am well equipped in PHP, MYSQL, JavaScript, JQUERY, AJAX & designing through Adobe Photoshop, including HTML5, CSS2/3, Bootstrap (responsive sites).
If you can come on chat and share the required customizations with a few details, I can check them right away and suggest you the time it will take.
Waiting for a positive response.
Thank you
Shailendra
