Shopify Speed & Core Vitals Optimization

My Shopify storefront feels sluggish across the board—homepage, every product page, and even the checkout flow—and Google’s Core Web Vitals are flagging it. I’m looking for someone who can dive into the theme code, apps, images, and any render-blocking assets to push Largest Contentful Paint, First Input Delay, and Cumulative Layout Shift into the “Good” range on PageSpeed Insights.

Here’s what I need from you:
• A quick audit outlining the biggest bottlenecks.
• Clean, lightweight code tweaks or theme refactoring where necessary (Liquid, JavaScript, CSS).
• Image and media optimisation without downgrading visual quality.
• App and script pruning—keep only what’s truly adding value.
• Final test results that show improved scores for LCP, FID, and CLS on both mobile and desktop.

If you’ve already lifted other Shopify stores to pass Core Web Vitals, let me know how you approached it and roughly how long it took. I’m ready to give you full collaborator access as soon as we agree on the plan, and I’ll judge success by the before-and-after Lighthouse metrics.
