Custom Mobile E-Commerce App

I’m launching a dedicated mobile store and need an experienced developer to turn the concept into a fully functioning e-commerce app. The core objective is simple: let shoppers browse products, add items to a cart, and check out securely—everything wrapped in a clean, intuitive interface that carries my existing brand style.

I haven’t settled on a platform yet, so I’m looking for your guidance on whether native iOS, Android, or a cross-platform framework (Flutter, React Native, etc.) will offer the best balance of performance, cost, and long-term maintainability.

You’ll receive:
• Brand guidelines, product images, and catalog data (CSV / API)
• Access to my current web store’s back-end for any necessary integrations

Deliverables:
• End-to-end app build (front-end and any required back-end services)
• Secure sign-up/login and payment flow
• Polished UI/UX that feels native on every chosen platform
• Assistance with App Store / Google Play deployment
• Full, well-documented source code in Git

Acceptance criteria:
1. Users can discover products, add to cart, and complete real transactions without errors.
2. App meets current App Store and Google Play review guidelines.
3. Code is clean, commented, and handed over in a private repository.

If you’ve shipped e-commerce apps before, especially those with smooth checkouts and responsive catalogs, I’d love to see examples. Let’s discuss your proposed tech stack, timeline, and any questions you have so we can get this rolling quickly.
