NexusERP

NexusERP is a full-stack enterprise project and portfolio operations platform built to demonstrate production-grade MEAN architecture. The Angular 15 frontend provides an executive dashboard, searchable project register, nested project workspaces, approval workflows, and a drag-and-drop task board with virtual scrolling. NgRx Entity, Store, Effects, selectors, and a facade manage normalized application state, asynchronous workflows, optimistic updates, and API failure recovery. The Express and MongoDB backend exposes a versioned REST API with DTO mapping, validation, pagination, search, JWT authentication, refresh-token rotation, role-based authorization, password recovery, security headers, and structured error handling. The project also includes zero-setup demo data, automated frontend and backend tests, Docker deployment files, API documentation, architecture guides, and extensive Angular revision material.
