I’m building a single digital ecosystem that merges several partner stores under one roof and doubles as a command centre for shoppers. Visitors must be able to browse a shared catalogue, find products quickly, and move through a checkout flow that hands orders to our offline fulfilment network. Before purchasing, they can even book a free doctor consultation through an integrated scheduler. The overall feel should strike a balance between simplicity and depth: first-time users see a clean, welcoming interface, while power users can dig into advanced filters, rich product data, and order-tracking tools when they choose. Core functionality I need: • Product search and discovery that pulls live stock from each connected store. • Seamless multi-store integration so one basket can contain items from several vendors. • A scheduling module for doctor consultations, complete with reminders and calendar sync. • A content hub where I can post customer testimonials and short video tutorials to reinforce trust. Please build on a modern, scalable stack (React/Next, Vue/Nuxt, or similar paired with Node, Laravel, etc.). I’ll need an admin dashboard for onboarding new stores, managing catalogues, approving consultation slots, and publishing content—no developer should be required for routine updates. Acceptance criteria: 1. Responsive UI that passes cross-browser and mobile testing. 2. Real-time inventory sync demonstrated with at least two sample stores. 3. End-to-end doctor-consultation booking, including confirmation email. 4. CMS lets me upload a testimonial video without touching code. 5. Source code in GitHub and live deployment with CI/CD enabled. Share your proposed architecture, timeline, and any relevant portfolio pieces so we can get started right away.
