I’m planning to launch a full-featured grocery and prepared-food delivery service and need a complete mobile solution that works seamlessly on both iOS and Android. The build should include a companion admin panel where I can track incoming orders, update their status, and manage users without touching the database directly. Here’s the scope as I see it right now: • iOS & Android apps: clean UI, fast loading, and compliant with the latest App Store and Play Store guidelines. • Web-based admin panel: secure login, dashboard showing real-time orders, user list with edit/disable options, and basic analytics to help me monitor growth. • Source code, build files, and deployment support all the way to publication. I’m flexible on the tech stack—native (Swift + Kotlin) or a cross-platform framework like Flutter or React Native—as long as performance and maintainability stay high. To keep the project on track, please outline your proposed architecture, major milestones, and any third-party services you’d integrate. If you have live examples of similar delivery apps, I’d love to see them.
