first of all, i think you made it over complicated. just gh-pages and cloudflare would work very well. you might need raw storage for your images and stuff use something like imgur.

increase those: - number of external links in your website - number of links to your website from external resources make them available in your public profile, fb, twitter, linkedin, github etc.

make your site multi paged somehow. so it will seen as resourceful (eg. you can make intro in the main page but add pages that explains how you did in some project and link them with first page)

include links of websites of companies you worked for

for fonts use googlefonts or some cdn, use same stuff for external resources this will have your site linked with billion visitor domains

have proper mobile version have https properly configured with hsts ^ these are important, use page speed insights to increase those

btw i didnt do anything much but when searched my domain comes in #3rd place, first 2 are linkedin and github. name is "mert akengin" domain is n0pe.me for reference.
