E-commerce Microservices Architecture
An online store split into microservices: catalog, cart, orders, payments and search, with Kafka events connecting them to shipping and notifications.
Checkout and Payment Sequence
What happens when a shopper clicks Pay: stock is reserved, the payment is authorised, the order is created and stock is released again if payment fails.
Order Lifecycle State Machine
Every status an online order moves through, from placed to delivered, including cancellations, returns and refunds.
Product Catalog Database Schema
A flexible product catalog: categories, products with variants (size, colour), prices, stock per warehouse and images.
Omnichannel Inventory Sync
How stock stays in sync across stores, warehouses and marketplaces so the same item isn't sold twice.
Returns and Refunds Workflow
How an online store handles a return: eligibility, pickup, quality check at the warehouse and the refund or replacement.
Product Recommendation Engine
How an online store builds 'recommended for you' and 'frequently bought together': click and order data, model training and a fast serving layer.
Flash Sale Scaling Deployment
How an online store survives a flash sale: CDN, a virtual waiting room, autoscaling and a queue in front of the order system.
Omnichannel Retail POS Architecture
A retail system that connects in-store POS, the online store and the warehouse: one customer, one stock pool, click-and-collect and returns anywhere.
E-commerce Customer Journey Map
The stages of an online shopper's journey and what the store does at each one, from discovery to repeat purchase.
E-commerce Sales Funnel
