Optimize Shopify Store Speed

I need an expert to further enhance my Shopify store's speed. I've already compressed images and removed unnecessary apps, but the site is still somewhat slow.

I have tested the speed using Google PageSpeed Insights.

Ideal skills and experience:
- Shopify development expertise
- Experience with both frontend and backend optimization
- Familiarity with speed testing tools like Google PageSpeed Insights

Looking for effective solutions to significantly boost my store's performance.
