Lighthouse expert to increase WordPress speed to 100 on mobile

Hello,

We are looking for a website speed optimization expert to help us increase our mobile performance ranking in Google Lighthouse.

We are using the inbuilt lighthouse speed checker in Google Chrome browser.

As shown in the attached screenshots, our current Lighthouse rankings are 90 on mobile and 97 on desktop.

Currently, the major problems we are facing are:

1. Excessive DOM Size
2. High Cummulative Layout Shift
3. High initial server response time
4. More Render-blocking resources
5. High main-thread work

We would like you to document your process, and make sure everything fits in our Tech stack, and within Kinsta's guidelines.

We are using WordPress, WP Rocket, Perfmatters, and Kinsta hosting.

Please include an example of a website you optimized to 100 raking on Lighthouse mobile.

We are willing to increase the budget.

Thank you.
