Shopify Safari-Compatible Review System

I need an engineer who understands Safari and WebKit inside out to help me extend a Shopify store with a robust product-review and rating feature. I am already running the core e-commerce flow; what is missing is a seamless, responsive review layer that behaves perfectly in Safari on macOS and iOS while remaining solid in the other major browsers.

Here is what I am after:

• A custom JavaScript module (vanilla JS or a lightweight framework) that lets shoppers leave star ratings, write comments, and view aggregate scores in real-time.
• Styling that matches my current Shopify theme, with no layout shifts in Safari’s rendering engine.
• Event tracking hooks so I can feed review data into existing analytics.
• A small admin utility—built with Shopify Admin APIs—that allows me to moderate or reply to reviews without leaving the back office.
• Browser-level QA, with special attention to WebKit quirks such as third-party cookie handling, viewport units, and touch events.

If you have deep experience solving Safari/WebKit issues and have shipped JavaScript features on Shopify before, please tell me about the most challenging compatibility bug you fixed. Remote collaboration is fine; when critical milestones approach, I can arrange brief on-site sessions.

I am looking for a long-term partner, so clean code, thoughtful comments, and proactive communication will weigh heavily in the selection. Let’s build something that feels native to every Apple user who lands on the shop.
