Senior React Native Developer – Migrate Base44 Web App to Production Mobile iOS + Android, Scalable

I need an experienced developer to migrate an existing Base44 (React + Vite) prototype to production-grade native mobile apps for both iOS (App Store) and Android (Google Play), with architecture built to scale. Scope of work: Export and thoroughly audit the Base44 codebase. Migrate frontend to production React Native (Expo strongly preferred) for iOS and Android. Migrate backend logic to a scalable solution (e.g. Supabase or equivalent). Implement and rigorously test permissions, privacy requirements, and store compliance for both platforms. Verify, harden, and optimize all API integrations. Battle-test features, edge cases, and performance across iOS and Android devices. Prepare full submission readiness for Apple App Store and Google Play. Provide architecture guidance for scaling to high user volumes. Must-haves: Multiple live React Native apps successfully published to both the Apple App Store and Google Play (provide links). Experience migrating from no-code/AI-generated or web codebases to cross-platform native. Strong backend experience with scalable solutions (Supabase, Firebase, Postgres, etc.). Deep expertise in mobile permissions, privacy compliance, and the full submission/review processes for both iOS and Android. Excellent code quality with TypeScript, modern React Native patterns, state management, and navigation. Portfolio + GitHub examples required. References from previous production mobile projects a big plus. Strong communication for phased collaboration with clear milestones. Engagement: Phased project (Audit & Plan → Migration → Polish & Testing → Launch Prep). Available ASAP. Remote OK with preference for EST/overlapping hours. Florida-based a plus but not required. To apply: Email/DM [your email] with: App Store and Google Play links + relevant GitHub/portfolio Brief summary of relevant migration or scaling experience High-level proposed approach Availability ASAP
