Hello,
I am a web designer and web developer, I can optimize your Wix website, the slow performance can be due to images that are not optimized, etc. I can start right away.
We can discuss any details over chat.
I have experience designing and building beautiful, clean, responsive and modern websites, using WordPress, HTML, CSS, Bootstrap, JS, JQUERY, PHP, MYSQL, etc.
I look forward to working with you!
