Multi-Tenant Task Management System

A full-stack task management application where multiple organizations (tenants) can use the same system with fully isolated data.

Features

• User Authentication — Register/Login with JWT tokens
• Multi-Tenant Isolation — Each organization's data is completely separated
• Role-Based Access Control — Admins see all org tasks, users see only their own
• Task CRUD — Create, view, toggle status, and delete tasks
• Modern UI — Dark glassmorphism theme with smooth animations

How Multi-Tenancy Works

Every user and task has an organization field. All database queries include this field to ensure data isolation between tenants. This is the "shared database, shared collection" multi-tenancy pattern.
