Though I mostly worked outside marketplaces, I have a lot of experience in Upwork also. Please contact me to see my Upwork profile. I can do anything on Magento and WordPress as I have a lot of experience. I use neat and clean, optimized, SEO friendly, w3 validated coding. My WordPress and Magento skills include (but are not limited to as I can do anything in WordPress and Magento): 1. Theme design and customization. 2. PSD to WordPress and Magento theme. 3. Plugin /extensions creation and customization. 4. Bug fixing. 5. Speed optimization. *As designing is very easy for an expert programmer as it requires skills mostly in CSS and HTML which is very easy compared to programming.

I can increase the page speed score to 90+ for mobile and desktop. Most programmers are limited to using speed optimization plugins. I have strong knowledge of SEO too.

I worked to improve page speed insight and GTMetrix score and make it highest possible fast to load. I also solved problem for LCP & TTFB in Core web vitals in google search console. I worked for the project titled  "Speed expert to improve Aggregate LCP and TTFB" in Upwork. 

Though the website has many bad things for speed like hosted on shared hosting, 10 plugins, a lot of images, many external server scripts etc but it has very high page speed score and it is high fast to load. 
High page speed score can't make high fast to load on mobile. But this site also fast to load on mobile device (load time below 2 seconds). For core web vitals (LCD, FID and CLS) in google search console, it needs to be faster on mobile too. Otherwise core web vitals in search console shows errors.

Please see my upwork profile with a lot of work history and excellent feedbacks https://www.upwork.com/fl/subir

Page speed work on wordpresss/woocommerce site.
Before my work load time waas 4-8 seconds.
After my work load time is 555 ms.
Website: https://lumaira.com/

Website speed depends on both website content and web server performance. There are a lot of works in both sides to make a website highest possible fast to load. Even every line of coding can help improve load time. As I am an advanced level programmer, I can do a lot of things to make highest possible fast to load.
