Customize CodeCanyon E-Commerce App

I already have (or will shortly purchase) an e-commerce app source code from CodeCanyon and need a developer who can turn that raw package into a fully functioning, production-ready application.

Scope of work
• Set up the entire project environment, resolve any dependency issues, and compile a clean build.
• Configure a minimalist design theme so the interface stays sleek and distraction-free.
• Activate and test three core features shipped with—or to be added on top of—the template:
– Payment gateway integration (please suggest the most straightforward option; Razorpay, Stripe or PayPal are all acceptable as long as checkout is seamless).
– User reviews with star ratings and editable comments.
– Product recommendations that surface related or trending items.
• Brand customisation: replace default logos, colour accents, splash screen and app name.
• Provide a signed APK/AAB (or iOS equivalent if the template supports it) plus the updated source code and a brief hand-off document summarising build steps and API keys/variables I need to maintain.

Acceptance criteria
1. The app installs without crashes on current Android devices (and iOS if included).
2. Each listed feature works end-to-end and persists data correctly.
3. UI follows a clean, minimalist look consistent across all screens.
4. All hard-coded CodeCanyon demo assets are removed or rebranded.

If you’ve worked with CodeCanyon templates before and are comfortable in Android Studio, Xcode, Flutter or React Native, let me know your estimated turnaround and any prerequisites you’ll need from my side (icons, payment credentials, etc.).
