Website signup built with auth0 + some firebase interaction with a table to display user's assets

I have already built the majority of a website + the back-end for it. It's a website that allows you to store gift cards in a wallet and it has a completed accompanying chrome plugin that allows you to apply these gift cards to checkout. It's 99% finished - I am looking for a web dev to finish the unfinished parts while I finish the back-end. What I need is a web dev to: 1 - Create a sign-up page on the website that registers registers users in my firebase account + signs them in once they register. (Ideally with an email verification email sent out to their account + welcome email that we have already designed also sent out - support for this would be great). I'd like to use auth0 for this so we can make it that when you're logged in to the website it also signs you in to the chrome plugin (I can send through the whole codebase for the chrome plugin - it is complete, well documented and quite short - I just need it to interact with the same auth0 token that the website uses so that a login in one will log you in on both). 2 - Take the 'wallet' page I have already designed and make it so it displays only cards that are in that user's account's wallet (on firebase - also already created). And displays "you have no active cards" otherwise. There are two wallets, the active wallet and the archived wallet - cards can move between and are displayed in each. Also there is a modal I've created for adding cards manually - so you can add a card manually to the user's firebase on the back-end. As most of the design + code for this is already written, I really just need someone to fill in these final parts. Please let me know if this is a job you can take on and I can send through the relevant materials. + Firebase logins + webflow logins (if you want to interact with the webflow page directly) or html exports from webflow + the codebase for the plugin if you need to work with the same auth0 tokens. Thank you, let me know your rate for this.
