I’m turning a concept into a working mobile application that runs natively on both iOS and Android. The very first milestone is to set up a clean, maintainable codebase and wire in secure email-and-password authentication. I’m flexible on the tech stack—whether you prefer Flutter, React Native, Kotlin Multiplatform, or another cross-platform framework—so long as the result feels native, performs smoothly, and can be extended easily. Deliverables • Single codebase compiling for iOS and Android • Onboarding flow: sign-up, sign-in, password reset, session persistence • Placeholder home/dashboard screen ready for future features • Well-commented code pushed to my private Git repo with clear build/run instructions I’ll consider the job complete once I can pull the project, build it locally, and log in on both devices without errors.
