Hey luna,
Thanks for your answer, im currently using impulse theme, I have 17 app running and im using them, actually all 4 culprits apply to my store, but I designed my store so good that I don’t want to change the designs or filles, I was hoping that i can optimize my store even with all the features included. Thanks for the list of Shopify experts, ill be looking into that. 
Thanks in advance.
