Developer needed for Base44 Replatform and React Native SaaS App Migration

Project Brief: Base44 SaaS Web App to self hosted AWS platform Migration and React Native SaaS App Migration 1. Overview & Context • Current Platform: Built as a responsive web application on Base44. • Project Goal: Migrate the existing web application out of Base44 and create a native, production-ready mobile application using React Native. • Current Traction: Zero active users. There is no live production database or user traffic, meaning this is a clean-slate architectural migration with zero downtime constraints. • App Category: Simpler SaaS tool (not a complex multi-vendor marketplace or intensive social network). 2. Target Technical Stack • Frontend: React Native (Expo framework preferred for faster cross-platform iOS & Android development). • Backend & Database: Supabase (or equivalent managed PostgreSQL database provider). • Hosting/Infra: Managed cloud database setup, with the front-end code wired for future App Store submissions. 3. Core Scope of Work Required I require a UK-based agency to handle the end-to-end migration process, including: • Code Export & Refactoring: Exporting the current codebase from Base44 via GitHub and refactoring/cleaning the code to strip out platform-specific boilerplate. • Database Setup: Recreating the database schema and implementing secure User Authentication (Sign up/Login) natively within our new managed Supabase environment. • UI/UX Porting: Translating our existing web/mobile-responsive frontend elements into performant, native React Native components. • Handover: Full delivery of source code repository ownership and managed database administrative access. • Store Deployment Support: Apple App Store and Google Play Store submission processes and Reveunecat integrations
