I’m planning a responsive web app that lets customers build their ideal cake online and check out in a single, elegant flow. The core journey begins with a live configurator where users choose the Size, Flavor, and Decoration of the cake, optionally upload a reference photo, review dynamic pricing, then pay and schedule delivery. The interface has to feel fresh and modern, work flawlessly on desktop and mobile browsers, and switch instantly between English and Arabic. Behind the scenes, an admin dashboard should surface every order, payment status, and delivery slot so I can adjust or confirm details in real time. Here’s what I consider the MVP scope: • Modern UI that carries the brand’s personality yet keeps navigation friction-free • Customization steps: size, flavor, decoration + photo upload • Secure checkout (card / wallet) and delivery scheduling • Bilingual support (EN/AR) with RTL alignment where needed • Admin panel for order management, status updates, and basic analytics Please tell me: 1. The e-commerce or food-delivery projects you’ve shipped that best match this flow. 2. Which tech stack you’d propose and why. 3. A realistic timeline and cost to deliver the MVP described above. I’m ready to move quickly once I see a clear plan that balances speed, quality, and future scalability.
