Grocery Delivery App Development

I'm looking for a skilled mobile app developer to create a basic single vendor grocery delivery application for a small business focusing on North-Indian/Asian grocery products in the Croydon area (5-10 km radius). The app should provide a seamless experience for users to browse products, add items to their basket, checkout, and track their orders.

Key Features:
- **Real-time Inventory Updates**: The app needs to sync with a Google Sheets CSV, where store owners manage stock levels.
- **Product Imaging**: Product images should be sourced from competitor apps or captured manually.
- **Cross-Platform Compatibility**: The app needs to be developed for both iOS and Android using Flutter.
- **User Authentication**: Users should be able to sign in using their email and password.
- **Payment Integration**: The app should support payments via Stripe.

Ideal Skills:
- Proficiency in Flutter for cross-platform mobile app development.
- Experience in creating e-commerce or delivery apps.
- Skills in real-time data syncing and API integration.
- Ability to implement secure user authentication systems.
- Knowledge in integrating various payment gateways, particularly Stripe.
