Headless shop architecture

Hi everyone, first post here!
I’m a frontend developer who never used shopware.
I was approached by a customer who wants a shopware with a blazing fast frontend.
I know that shopware 6 offer a vue storefront but the thing is that I normally work with React and I want to develop the frontend using Gatsby.
I would like to have some suggestions on that. Apart from my gratitude, if I click with someone who is wishing to do some freelancer work, this could be a great opportunity to work together.
