I need a frontend and backend for a WEB3 project app that supports both Android and IOS.

It's roughly three pages. The first page handles NFT selection and composition, announcements, and rankings. The second page has features for viewing ads and MintNFT. The third page is for logging in and displaying the NFTs currently held by the user. The overall design is very simple. I will provide all contract addresses and ABIs; you just need to help me with the code for both front-end and back-end. The app supports multiple languages (but you only need to write it in English). The language functionality needs to be written separately for easy integration of additional languages. To summarize: after logging into the Android or IOS app, Metamask or TP Wallet will be invoked for authorization. Web3 code will then be used to call the contract ABI processing upgrade and Mint code. Finally, the backend handles login, rankings, ad points, and announcements.
