A full-stack e-commerce platform built from scratch Django REST backend with inventory management, order processing, and delivery tracking, paired with a Next.js storefront and an admin dashboard. Built as a personal project to design and implement a complete commerce system end-to-end.
E-commerce projects are often tutorial-depth they stop at cart and checkout. The goal here was to build the full operational stack: not just the customer-facing storefront, but the inventory system, order fulfillment pipeline, delivery tracking, and admin reporting that a real business actually needs to run.
- Built a Django REST backend with a product catalog, variant management, inventory tracking, and order state machine.
- Designed a Next.js storefront with cart, checkout, and order history optimized for fast page loads with static generation.
- Implemented an admin dashboard covering product management, order processing, and live inventory counts.
- Built a delivery tracking module with driver assignment, real-time status updates, and customer-facing delivery notifications.
- Added a reporting layer with daily revenue summaries, top-selling products, and inventory restock alerts.
Beyond Cart and Checkout
Most e-commerce tutorials end when the order is placed. The interesting engineering problems come after what happens to inventory when an order is placed? What if it goes out of stock mid-checkout? How does the delivery driver get assigned? How does the customer know their order is on the way? This project was built specifically to answer those questions.
The storefront and order management system from product listing through to delivery confirmation.
Product catalog management and the order processing dashboard with state machine controls.
Inventory State Machine
The inventory system uses optimistic locking to prevent overselling when a customer adds an item to cart, a soft reservation holds the stock for 15 minutes. Checkout converts the reservation to a committed deduction. If the customer abandons the cart, the reservation expires and stock is released automatically. This prevents both overselling and phantom stock locks from abandoned sessions.
Delivery Tracking
The delivery module assigns orders to drivers from a pool, tracks delivery status through a state machine (Assigned → Picked Up → In Transit → Delivered), and sends customers SMS and email notifications at each state change. Drivers update order state via a lightweight mobile-optimized interface no native app required.
The platform successfully demonstrates a production-grade e-commerce architecture. The inventory management and delivery tracking modules went beyond typical tutorial scope, establishing patterns applicable to real commerce deployments.
