Squarespace Speed Optimization Expert Needed 90+ mobile and desktop

I'm in need of a skillful Squarespace expert who can boost my website's speed significantly. The aim is to achieve a speed rating of 90+ on both mobile and desktop.

Key Aspects of the Project:
- Specific Pages: The optimization should be focused on three main sections of the site - the home page, product pages, and blog pages.
- Features and Functionalities: I'm particularly looking to optimize image loading, video loading, and any animation effects on the website.
- Current Loading Time: The website's current average loading time falls between 3-5 seconds, but I'm looking to get it well under 3 seconds for an improved user experience.

Ideal Skills and Experience:
- Proven experience in Squarespace speed optimization is a must.
- Familiarity with optimizing image and video loading as well as animations on Squarespace.
- Ability to meet and maintain a speed score of 90+ on Google's PageSpeed Insights tool for both mobile and desktop.
- Excellent communication skills and professionalism as I value clear and timely updates on the progress of the project.

If you're confident in your ability to deliver on these requirements, I'd love to hear from you.
