I need a seasoned cross-platform developer who can take an idea from sketch to App Store and Google Play release using a single codebase. The end result should feel completely native on both iOS and Android—smooth animations, fast load times, and full compliance with each store’s guidelines. You’ll guide the technical stack choice (React Native, Flutter, or similar), set up the project, build out the UI, connect any required APIs, and implement analytics and crash reporting. Expect to manage the full cycle: coding, unit testing, device testing, store-ready builds, and post-launch bug fixes during the warranty period. Deliverables • Complete source code in a shared repo • Release-ready builds for iOS and Android • Basic setup documentation and store submission notes If you have apps live on both stores that showcase tight performance and modern UX, link them in your proposal so I can get a feel for your work.
