24-Hour E-Commerce App Build

I have exactly one day to put a working e-commerce app in people’s hands and need someone who can move at the same speed. The build must install and run on both iOS and Android. Whether you choose Flutter, React Native, Swift/ Kotlin, or another framework is up to you—as long as what you deliver is stable and ready for store submission or direct distribution.

What I will hand over the moment we start:
• Brand assets, basic style guide, and product data in JSON.
• REST API endpoints for catalogue, user auth, and checkout.
• Apple and Google developer-account access for signing and test uploads.

What I need back within 24 hours:
• Complete source code.
• Signed builds (.ipa for TestFlight, .apk or .aab for Google Play internal testing).
• A brief README so I can re-build and update products without your help.

Acceptance criteria
• App installs and launches without errors on recent iOS and Android devices.
• Core e-commerce flow—browse, select, and purchase—works against my live API.
• No hard-coded credentials; environment keys pulled from a config file.
• UI follows the supplied brand colours and fonts.

If you have a reusable template or starter kit that can shave hours off the clock, that’s perfect; the priority is speed with reliable code. Let me know right away how you plan to tackle the 24-hour window and what support you’ll need from me during the build.
