I’m building a complete developer-profile builder that runs as a mobile app with a React front-end and Firebase back-end. I already have the concept sketched out; what I need now is someone who can transform it into a polished, production-ready application and guide it all the way from an empty repo to a store-ready release. Here’s what the job looks like: • Design and code the entire UI in React (if you prefer React Native or Expo for the mobile layer, that’s fine—just specify your approach up front). • Set up Firebase Authentication, Firestore, and Storage so each user can log in securely, create their profile, and persist data in real time. • Wire everything together: profile fields, avatar upload, project sections, and any supporting views (dashboard, settings, etc.). • Configure Firebase Cloud Functions and basic security rules so the data model is safe but flexible for growth. • Package, test, and prepare the builds for both iOS and Android; fastlane, EAS, or other modern CI/CD tooling is welcome. • Deliver clean, well-commented code, a concise README that explains local setup and deployment, and a brief hand-off call or video walkthrough so I can maintain the project after launch. Acceptance criteria 1. A new user can register, complete a profile, and see it populate instantly on another device. 2. All profile data persists in Firestore and files in Storage with proper rules enforced. 3. The app installs and runs without errors on current iOS and Android simulators/emulators. 4. The repo passes an end-to-end test suite and static lint checks before final hand-off. If this sounds like your comfort zone, let me know your timeline and preferred toolkit and we’ll get started right away.
