I need a freelance mobile developer who can take my concept for a business-focused productivity app and turn it into a polished, high-performing product for both Android and iOS. The work spans the full cycle: shaping a clean, intuitive interface, writing robust cross-platform code (Flutter or React Native are both acceptable), wiring in our REST APIs and database layer, then testing, profiling, and fine-tuning until performance feels seamless. You’ll be fully responsible for: • A user-friendly UI that follows current platform guidelines • Solid, maintainable code that compiles to both stores • Secure API and database integration • Comprehensive QA with fixes for any crashes, lag, or edge cases I value clear communication, regular progress builds, and well-commented source code pushed to Git throughout the project. If you have a track record of shipping business or productivity apps and can work independently on a remote, freelance basis, I’d like to hear how you would approach the architecture, toolchain, and release plan.
