Speed Front End and Back End of WoocommerceWebsite

Hello! I'm looking for a freelancer to help me speed up my WordPress website front end (visitor) and backend (when processing posts, orders) without using conventional methods as right now most of those are installed (Nitropack, Cloudflare, Caching), will probably need to
1- Look at the plugins and theme code and determine what we need to do to make it perform better.
2- Provide a specific plan to improve speed
3- Get approval on plan from me
4- Execute plan
5- Show significant speed change
6- Customizations to code should be in child-theme or somewhere where any future updates to Wordpress will not reverse changes.
7- might need to update theme without breaking it

Current website hosting: Max Ram: 15GB, Process:
1,200/Min, Memory limit 768MB
