Challenge
- Inventory management must account for food-specific factors: expiration dates, refrigerated/frozen handling, and delivery time windows.
- Delivery availability and pricing logic by region and time slot is complex.
- Mobile orders account for 80%; UI speed and usability directly drive churn.
Solution
- Embedded expiration dates and storage temperatures in the product model; auto-determined order eligibility at display time.
- Defined delivery zones by postal code and combined them with a time-slot master for dynamic calculation.
- Used Next.js App Router for fast page transitions and delivered images through CDN with next-gen formats.
Technology Decisions
Why App Router
Server Components enable parallel data fetching, dramatically improving TTFB for product list pages. The UX gap is significant on mobile-first sites.
