Hey! I noticed you want a project simmilar with what I was recently involved in. You can check a screenshot of a mobile app for Android and iOS built on React Native that I helped build in my portfolio. I was involved in blockchain (ethereum) integration of the frontend and backend, building backend and frontend modules, app architecture planning, basically it was a 2 men job. The app includes: - ethereum smart contract for erc721 non-fungible (collectible) tokens - react-native frontend with clean design - NFC integration - blockchain integration - api I am a fullstack developer so I can also manage any develoment operations need like seting up servers, manging repositories, getting SSL certificates etc. And yes!
