I need a full-featured e-commerce application ready for launch no later than 20 February. Customers must be able to browse and purchase physical goods, then immediately schedule any or all of the following add-on services for each item: installation, repair or consultation. In this we will have 3 panels: 1 Admin Panel (overall access), 2 Service Center Panel (to track repairs and provide service), and 3 User Panel. Core flow • Product catalogue with rich search and filtering • Cart, checkout and secure payment gateway integration • Service booking tied to the purchased product, including calendar selection and real-time availability • Order and service tracking with push/email notifications • Admin area for inventory, pricing, promo codes, service slots and customer management Tech is your call—native iOS/Android, React Native, Flutter, or a responsive web stack—so long as it delivers a smooth user experience and can scale. I’ll provide product data and branding assets; you’ll handle architecture, UI/UX, development, basic QA and handing over source code plus deployment notes. Acceptance criteria 1. All purchase and service workflows run end-to-end without errors on the latest iOS, Android and modern browsers. 2. Admin panel lets me add/edit products, adjust stock, set service durations and approve bookings. 3. Payment and booking confirmations reach both customer and admin instantly. 4. Source code, documentation and one live demo build are delivered before the 20 February deadline. If you can commit to this timeline and ship a polished, reliable product, let’s get started.
