I need an experienced developer to turn my productivity-focused application idea into a polished, fully functioning product. The core goal is to help users work smarter and organise their day more efficiently, so intuitive UX and rock-solid performance are critical. I haven’t committed to a specific platform yet, so I’m open to your recommendation—whether that’s a native Android or iOS build, or a single cross-platform codebase with Flutter or React Native. Whichever route we take, clean architecture, maintainable code, and clear documentation are non-negotiable. To keep things straightforward, here’s what I expect at each stage: • Wireframes and a brief technical proposal so we agree on scope and features. • Iterative builds (alpha, beta, final) delivered through a shared repo so I can test in real time. • A release-ready build plus handover package that includes source code, build instructions, and a concise user guide. If you have proven experience shipping productivity apps—especially ones that handle tasks, reminders, or workflow automation—let’s talk details and timelines.
