Depending on the way the project is built, I can help with the Above the fold optimization for it. Basic service would imply modifying loading of JS, common Critical CSS, loading rest of CSS after main html and Above the Fold has completed, current images reprocessing, all basic Google Pagespeed rules respected. Extended service would add: recompile CSS to include strictly minimal needs, optimise JS only to the requirements of the website, integrate CDN of choice, make webfonts load without breaking Pagespeed score.
