I’m ready to build a complete, production-grade marketplace app for both iOS and Android that captures everything users like about the Nigerian Jiji platform while noticeably raising the bar on look-and-feel and day-to-day interactions. Core goals • A cleaner, more intuitive user interface that reduces the taps it takes to post, browse, and purchase items. • A real-time chat system so buyers and sellers can negotiate without leaving the app. • A transparent review and rating flow that lets users see credibility at a glance and quickly report bad actors. Scope of work – Design: Create high-fidelity UI/UX mock-ups, apply a modern design language inspired by top global classifieds apps, and hand off reusable style components. – Development: Code the entire solution for iOS and Android (native Swift/Kotlin or a robust cross-platform stack such as Flutter or React Native—open to your recommendation). – Core features: user onboarding with phone/email, item listing with image/video uploads, location-based search, in-app payments (Paystack preferred but flexible), secure real-time chat, push notifications, ratings & reviews, and an admin dashboard for moderation. – Security: End-to-end encrypted messaging, data at rest encryption, and basic fraud-detection hooks. – Testing & launch: Unit and integration tests, app-store compliance, and publication to Apple App Store & Google Play. Deliverables 1. Source code and build files for both platforms 2. Compiled apps ready for store submission 3. Admin dashboard (web or mobile) 4. Technical documentation and a brief hand-over call I’m looking for a partner with proven marketplace or social commerce experience who can guide architecture decisions, iterate quickly, and keep communication clear throughout the project. Please share links to relevant live apps, your proposed tech stack, and an estimated timeline to reach MVP and full release.
