Backend system for product management, orders, coupons, stock control, accounting, dashboard reporting, and Steadfast delivery integration.
Ladz is a production-ready e-commerce backend platform built to manage storefront operations, admin workflows, product catalogs, inventory, orders, payments, coupons, delivery operations, accounting records, and dashboard summaries from one structured system.
A backend-first summary of the product problem and the solution direction behind the full project delivery.
Ladz is a production-ready e-commerce backend platform built to manage storefront operations, admin workflows, product catalogs, inventory, orders, payments, coupons, delivery operations, accounting records, and dashboard summaries from one structured system.
The client needed a reliable e-commerce backend where admins could manage products, stock, orders, coupons, roles, delivery operations, and accounting without depending on disconnected tools or manual tracking. The system also needed a clean dashboard summary view and delivery workflow support through Steadfast courier API integration.
I developed a FastAPI-based backend with modular APIs for authentication, role management, product and category management, stock tracking, cart and favorite flows, order and payment processing, coupon logic, accounting cost entries, dashboard summaries, and Steadfast delivery service integration. Redis-backed optimization, JWT security, Dockerized deployment, and Nginx reverse proxy support were used to make the system reliable and scalable.
A single system architecture snapshot preserved as proof of the delivery design and implementation flow.
The stack used across the full build, covering service logic, data storage, infrastructure, cloud setup, frontend integration points, and delivery tooling.
The core capabilities were implemented as production-facing modules, shaped for real usage, maintainability, and future scale.
