I have finished UI designs ready to go and need them turned into a working product that runs smoothly on the web as well as native iOS and Android. The front-end should be built with React (React Native for the mobile builds is fine) and connect to a fresh Java-based backend backed by PostgreSQL. Because no server side exists yet, you’ll be setting up the whole stack—database schema, REST/GraphQL layer, authentication, and deployment pipeline. The screens are already laid out, so your focus is on faithfully reproducing the design, wiring up the flows, and making sure the codebase stays unified across all three platforms. I’m happy with standard tooling such as Spring Boot, Gradle or Maven, Docker, and Expo/EAS, but I’m open to suggestions if you have a smoother workflow. Please include: • Responsive React web front-end that mirrors the supplied Figma/PSD files • React Native builds ready for TestFlight and Google Play internal testing • Java (Spring Boot) API layer with clean, well-documented endpoints • PostgreSQL schema and seed data scripted for one-command setup • Basic user auth (JWT or OAuth2) and role management • README with environment variables, build commands, and deployment steps I’ll test by spinning the project up locally, hitting each API route, and running the mobile apps on device simulators. If everything matches the attached UI and the data persists correctly, we’re good to go. I also need it to be hosted in google.
