Hi there,
I can do the job for you. I have extensive experience optimizing websites and enhancing performance using best practices.
I had a look at your URL, as well as the GTMetrix report you had provided and additionally ran a fresh scan on the URL as well.
It looks like most of the issues you are facing are due to static assets/resource loading, and some heavy Javascript heavy lifting which is hindering with the initial page load time/speed.
Do you have a quantifiable state you wish to get to in terms of the desired performance/load times/speed etc in mind? The reason I ask this explicitly is because things like this are never ending and optimization can be carried on and on if specific requirements/specifications are not agreed up on.
If you could elaborate on what the desired end goal/result would be, it would help me assess the work involved and come up with an implementation plan accordingly.
Let me know if you have any questions. Look forward to hearing from you, and working with you.
Regards,
V
