Understanding The Problem & Our Approach

The Challenge

The brand\'s legacy monolithic store collapsed during major sale events. They needed a globally distributed system to handle high concurrent traffic without downtime.

Legacy Systems Scalability Issues Data Silos

Our Solution

We built a headless storefront coupled with edge-caching to eliminate single points of failure and reduce checkout latency by 87%.

End-to-End Technical Workflow

Customer grocery browsing, delivery slot selection, payment, picker assignment, substitution handling, and last-mile delivery.

01

Slot Selection

Delivery slot calendar shows real-time availability per postcode zone; slot reserved on checkout start.

Input: Postcode + Date
Output: Reserved Slot
02

Order Processing

Payment captured; pick list generated and routed to nearest dark store with optimal pick path.

Input: Confirmed Order
Output: Pick List + Route
03

Smart Substitution

OOS items trigger AI substitution suggestions; customer confirms via push notification within 2 minutes.

Input: OOS Event
Output: Approved Substitution
04

Last-Mile Delivery

Driver assigned via optimised routing; live GPS shared with customer; delivery confirmed via OTP.

Input: Packed Order
Output: OTP Delivery Confirmation
