My Shopify store is suffering from slow performance due to scripts—and I’ve already pinpointed the specific scripts that are dragging load times down. Alongside that, a few CSS errors are creeping in and spoiling the visual polish. Here’s what I need: • Optimise or replace the identified slow JavaScript files so pages render snappily without breaking existing functionality. • Tidy up every CSS error you encounter, ensuring consistent styling across all devices. • Provide before-and-after speed metrics using Shopify’s analyser, Lighthouse, or a similar tool so we can see the real gains. • Document the key code changes in a brief hand-off note so I can maintain the improvements long-term. You’ll have full theme and asset access in a staging environment the moment we start. Please let me know your estimated turnaround time and any examples of previous Shopify optimisation work you’re proud of.
