You can hire someone from Shopify Experts or see if someone from Shopify Community can help you.

Reducing unused JavaScript and CSS on your Shopify store's homepage, product page, and collection page can help improve your website's loading speed and overall performance.

Here are some steps you can follow to achieve this:

1. Use a performance analysis tool
Use a performance analysis tool like Google PageSpeed Insights, GTmetrix to identify the unused JavaScript and CSS on your website. These tools will give you a detailed report of what files are being loaded on your website and how long they take to load.

2. Minimize your files
Once you have identified the unused files, you can minimize them by removing unnecessary code and comments, combining multiple files into one, and minimizing white space. This will reduce the file size and load time of your website.

3. Use lazy loading
Use lazy loading to delay the loading of images and other media until they are needed. This can significantly improve your website's loading speed.

4. Remove unused apps and themes
Unused apps and themes can add extra code to your website and slow down its performance. Remove any apps and themes that you're not using to reduce the amount of JavaScript and CSS on your website.

5. Optimize images
Large images can slow down your website's loading speed. Optimize your images by compressing them, reducing their size, and using the correct file format.

6. Minimize HTTP requests
Each time your website loads, it makes multiple HTTP requests to load different resources. Minimize these requests by combining multiple files into one and using CSS sprites to reduce the number of image requests.

Overall, optimizing your website's performance is an ongoing process that requires monitoring and tweaking over time. By following these steps, you can reduce unused JavaScript and CSS on your Shopify store's homepage, product page, and collection page, and improve your website's loading speed and user experience.
