I'm expert in speed optimization for WordPress based websites.
I'll get your website optimized for speed, not only by using your W3 total cache, but other tools at my disposal as well.
My knowledge in the IT sector (javascript, WordPress, CSS, HTML...) is extensive.
I have experience in speed optimizing WordPress websites, on Upwork, I did 3 jobs like this last week.
Feel free to contact me if you have any questions.
