I’m ready to bring a same-day “quick commerce” experience to the auto-parts world and need a full mobile build that launches on both iOS and Android from day one. The core flow is straightforward: • Shoppers browse a real-time product catalog, filter or search for specific parts, and see live stock status. • Secure account creation/login keeps their carts and orders in sync across devices. • Built-in payment processing (cards and popular wallets) completes the checkout without leaving the app. • Once an order is placed, customers track every step—from warehouse pick to courier hand-off—through an in-app timeline and push notifications. Clean architecture, fast load times, and a UI that feels as smooth as the best food-delivery apps are non-negotiables. If you’ve shipped production apps with catalog search, real-time tracking, and payment gateways before, let’s talk about your proposed tech stack, milestones, and how quickly we can reach the first TestFlight / Play Console build.
