• Secure login/logout
• Create, read, update, and delete tasks
• User-specific task lists
• Responsive, clean React frontend
• Protected routes for authenticated users

• Frontend: React, TypeScript, Vite, React Router, React Toastify
• Backend: Node.js, Express, MongoDB, Mongoose, JWT, bcryptjs
• Styling: CSS Modules

• Node.js (v16+ recommended)
• npm
• MongoDB database (local or Atlas)
