Woocommerce Website Optimization

General information for the website: Woocommerce
Kind of development: Customization of existing website
Description of requirements/features: I need someone to optimize the wocommerce without installing any extra plugins. Optimization should be done on code level and not with the help of plugins/W3T/CDN/Others.

Requirements:
1. "A" on PageSpeed Score and YSlow Score (GT Metrix)
2. "A" in All (http://www.webpagetest.org/)
3. Mobile 80+ and Desktop 90+ (Google page insights)
4. Reduce website page size from 1.8 MB to <1.00 MB
5. Reduce number of request from 120 to <60
6. Should be W3C Compliant

Important Task TO Perform:
1. Minimize HTTP requests
2. Use Gzip compression
3. Use HTTP caching
4. Move all CSS style rules into a single, external and minified CSS file
5. Minify all JS files and, if possible, try combining them into a single external JS file
6. Include external CSS files before external JS files
7. Place your JS scripts at the bottom of your page
8. Optimize images
9. Reduce redirects
10. And On page is not perfect, we need to update On page meta tags are missing
11. Minify JavaScript: Compacting JavaScript code can save many bytes of data and speed up downloading, parsing, and execution time.
12. optimize the images: Properly formatting and compressing images can save many bytes of data.
13. Compacting HTML: Compacting HTML code, including any inline JavaScript and CSS contained in it, can save many bytes of data and speed up download and parse times.
14. Minify HTML: Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.
15. Prioritize visible content: Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.
16. Minify CSS: Compacting CSS code can save many bytes of data and speed up download and parse times.
17. Leverage browser caching: Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
18. Eliminate render-blocking JavaScript and CSS in above-the-fold content: This causes a delay in rendering your page.
19. Reduce the redirect Url's on page because it increase the download or execution time.
20. Add Expires headers: Expires headers tell the browser when to serve a cached version of the page or not.
21. Use cookie-free domains: Where possible serve static content from other domains to avoid unnecessary cookie traffic.
22. Remove duplicate Javascript and CSS
23. Avoid empty src or href
24. Make AJAX cacheable
25. Eliminate render-blocking JavaScript and CSS in above-the-fold content: i handle this section with a plugin (use of WTC plugin its important issue)
26. Optimized pages, html and inline elements
