WordPress Performance Analysis & Optimization Expert Needed

I'm looking for a WordPress expert who can provide a thorough performance analysis of my site and offer optimization recommendations to fix the loading speed. Currently we are using WP rocket. but still seems to be loading issues on mobile and desktop.

The website is snrgroup.com. Please put keyword "SPEED" in your response so we can filter out automated responses.

Looking for someone who can help right away working with me now.

Thanks!
