Optimize Shopify Homepage Speed

I'm urgently seeking a Shopify specialist who can boost my website's homepage speeds- in particularly, my MOBILE SITE (although desktop site still needs improving). While I'm unsure of what's causing the slow load times, I'm open to you conducting a thorough analysis to identify culprits which could be a number of things!

Experience in:
- Shopify platform
- Image optimization
- Plugin management
- Identifying and resolving script issues

If you can bring a swift and effective solution, please bid!
