I’m building an astrology application that needs to run smoothly on iOS, Android, and the web from a single, maintainable code-base. The scope covers everything from the first clickable prototype to store-ready builds and a live, browser-based version that mirrors the mobile experience. You’ll be responsible for: • Developing the cross-platform front end (Flutter, React Native or a similar framework—open to your expert recommendation) • Setting up the lightweight back end and API endpoints that deliver content to all three clients in real time • Implementing secure user accounts with social sign-in, email verification, and basic profile management • Preparing the iOS and Android packages for App Store and Google Play submission, and deploying the web build to a production domain • Providing clean documentation so future content or feature expansions can be added without rewriting core logic Acceptance criteria: 1. One code-base produces three stable builds (iOS, Android, web) with identical functionality and design. 2. All network calls, authentication flows, and analytics events succeed on devices running the current major OS versions. 3. Source code is delivered via a private repository along with a brief setup guide that allows me to compile fresh builds locally. If you have prior experience shipping consumer apps across these exact platforms, I’d love to see a link or two—otherwise a quick outline of your proposed tech stack will help me evaluate fit.
