I run a neighborhood grocery shop and want to give my customers a simple, modern way to shop from their phones. The app must let shoppers browse a full product catalog with images, prices, and real-time availability, place online orders for pickup or delivery, and read or leave customer reviews for each item. Account features are essential: customers should be able to register and log in, manage their profile details (addresses, saved payment methods, order history), yet still have the option to complete a purchase through a friction-free guest checkout when they prefer. I’m open to your recommendation on whether we build natively, cross-platform, or as a progressive web app—whichever you feel will best balance performance, cost, and speed to market. Please outline your proposed tech stack, timeline, and any previous grocery or e-commerce apps you’ve delivered. Key deliverables: • Fully functional iOS & Android build (or web app, if you advise that route) • Clean, well-documented source code ready for future updates • Admin access for product management and order tracking • Basic UI/UX aligned with our store’s branding Let me know what additional information you need and how quickly we can get a prototype in users’ hands.
