How hertilan/kaizen-be works

Kaizen BE is an Express backend for a business-management portal. A client request enters through the API server and a domain route, then a controller performs domain operations and accesses persisted records through Prisma; selected routes also apply authentication. The visible capabilities include general commerce, finance, supplier distribution, engineering project management, tasks, notifications, and exports. Controller and route files establish these domains, but only some controller implementations were sampled, so internal links are shown only where supported.
