I’m commissioning a full-cycle build of a mobile community app tailored to working professionals. The product must launch on both Android and iOS, ideally from a unified codebase such as Flutter, React Native, or another cross-platform framework you’re comfortable with. Core experience Users sign up, authenticate, and move through four main areas: a forum where they can post questions and reply in threads, a scrolling industry-style news feed, an events calendar, and a section that hosts on-demand training content. All screens should feel modern, fast, and consistent with current platform guidelines. Account structure • Basic accounts – free entry-level access • Premium accounts – extra features/content, unlocked through in-app purchase or subscription • Admin accounts – create, curate, and moderate all content from a simple browser-based CMS/dashboard Essential capabilities • Secure registration/login (email, social auth optional) • Role-based access that turns premium features on or off • Push notifications for forum replies, breaking news, or event reminders • Search, bookmarking, and basic analytics • Store-ready builds: APK plus TestFlight/IPA Deliverables include the complete, well-documented source code, final binaries ready for store submission, and a short hand-over guide so my in-house team can maintain content. Please outline your preferred tech stack, any similar apps you’ve shipped, and an estimated timeline for MVP through store approval.
