I own a busy local grocery store and want to scale my business with a dedicated mobile presence. The goal is a fully-featured app that runs smoothly on both iOS and Android. Core functionality must include: • Product listing and search so customers can browse our entire catalogue quickly. • Shopping cart and checkout that feels effortless and secure. • User account and wishlist so shoppers can save favourites and track orders. At checkout I need payment gateway integration that supports both credit/debit cards and digital wallets like PayPal. A clean, intuitive back-end that lets me add new products, update prices, and review orders in real time will be essential for day-to-day operations. Deliverables I expect: 1. Production-ready iOS and Android builds, tested and ready for App Store and Google Play submission. 2. Integrated payment processing for the methods mentioned above. 3. Source code and brief documentation so my team can perform routine updates. Use whichever cross-platform framework you’re most comfortable with—Flutter, React Native or a similar toolset—as long as performance remains smooth and the final design matches modern UI/UX standards. If you can demonstrate previous work on retail or grocery apps and outline a clear timeline, I’m ready to move quickly.
