ISDN Distribution System
A centralised, island-wide sales distribution management system.
Overview
ISDN manages sales distribution across the island from one place: stock, allocations, invoicing, deliveries and accounts, backed by SQL Server stored procedures and a JWT-secured Go API.
The challenge
Distribution across regions needs one source of truth for stock and orders, while each region works on its own.
What we built
A central SQL Server database with business rules in stored procedures and functions, a Go REST API with JWT authentication and live updates over WebSockets, and a React and Ant Design interface.
