WordPress (12 yrs)/Magento (10 yrs)/Python expert

Please see my Upwork profile with a lot of experience and excellent feedbacks: [login to view URL] At a glance: * Expert in WordPress (12 years), Magento (9 years), speed optimization (12 years), web server (12 years), python (5 years), mathematics, and physics. * Website speed depends on web server configuration & website content. I work in both of them to make a 90%+ page score for mobile & desktop. * I fix core web vital errors. * I use neat and clean coding, search engine-friendly coding, optimized coding, w3 validated coding. * Fluent in speaking, writing, listening, and reading English. * I AM A FULL-TIME PREFERRED FREELANCER & I WORK MYSELF. ---------------------------------------------------------- Magento/Woocommerce: ---------------------------------------------------------- 8 years experience in magento and 11 years in woocommerce. I can do anything in Magento & woocommerce Please see my Ecommerce Development profile for more details. ---------------------------------------------------------- WordPress: ---------------------------------------------------------- 12 years of experience in WordPress and I can do anything in WordPress. Please see my CMS Development profile for more details. ------------------------------------------------------------ Page speed optimization skill: ------------------------------------------------------------- Load time/page speed score of a website depends on a lot of factors in web server (CPU, number of CPU cores, CPU Clock Speed, ram, server configuration, server cache, etc) and website content (number of plugins (WordPress), images, pages, page content, etc). Even each line of coding can help improve load time. As I am an advanced-level programmer and I have 12 years of experience in speed optimization, web server and web programming, I can do a lot of work on both web servers and websites to make a site the highest possible fast to load. Only advanced-level programmers can work on both of them. * I fix the issues of LCD, FID and CLS of core web vitals in google search console. Website speed depends on the webserver and website content. There are a lot of works to make a website the highest possible fast to load. Even I can work every line of coding to make it faster to load. Some of the important works for speed improvement I do (but not limited to): 1. js/CSS/image optimization. 2. Image resizing. 3. cleaning and optimizing code. 4. Remove unused plugins and replace plugin functions with the theme. 5. Use any of the best cache plugins which is the best for your website. 6. checking webserver like CPU clock speed, ram, configuration, and fixing issues. 7. reducing server response time. 8. Cache implementation 9.CDN implementation (Cloudflare, stack path etc). 10. removing render-blocking script. 11. reducing first byte (TTFB). 12. remove unused CSS and js.
