Cross-Platform Quick Commerce Mobile App

I’m building a quick-commerce application focused on fast product delivery, and I need a developer who can take it from wireframes to a polished release on both iOS and Android. The core shopping flow should feel effortless: users open the app, browse items by clear categories, refine results instantly with a search bar, and discover additional products through personalised recommendations.

Here’s the experience I’m aiming for:
• Fast onboarding (phone / email login)
• Real-time catalogue pulled from our backend API
• Cart, checkout, multiple payment gateways, and order-tracking push notifications
• Geo-based delivery slots and live rider tracking
• Clean, responsive UI that follows Apple Human Interface Guidelines and Android Material Design while still feeling like the same brand on both platforms

You’re free to use Flutter, React Native, or Kotlin/Swift + shared code where sensible—as long as performance is smooth and app store standards are met.

Deliverables I expect:
1. Source code with clear modular structure
2. Build-ready apps for the App Store and Google Play
3. Basic unit tests around critical purchase flows
4. Brief hand-off document and a walkthrough call so my in-house team can maintain future iterations

If you’ve shipped a similar high-traffic commerce app and can demonstrate fast, reliable deployments, let’s discuss timelines and milestones.
