Task Manager

Overview

Nexus Tasks is a full-stack task management application designed to support workspace-based collaboration. Unlike basic to-do apps, this system introduces isolated workspaces, role-based user management, and real-time notification workflows.

The goal was to build a production-level application that handles authentication, team collaboration, and scalable task management in a clean and modern UI.

Tech Stack

Frontend: React, Vite, TypeScript, Tailwind CSS v4, Framer Motion, Zustand, ShadCN UI Backend: Node.js, Express Database: MongoDB (Mongoose, MongoDB Atlas) Authentication: JWT, bcryptjs Notifications: Novu (email + in-app) Deployment: AWS EC2 (backend), Vercel (frontend)

───────────────────────────────────────────────────────

Key Features

- Workspace-based multi-user system - Secure authentication with JWT and hashed passwords - Password reset flow using Novu email workflows - Task CRUD with status tracking and assignments - Team management (invite, update, remove members) - Real-time notification inbox - Global search, filtering, and sorting - Modern glassmorphism UI

System Design

The system follows a modular full-stack architecture:

- Frontend handles UI state using Zustand and communicates with REST APIs - Backend manages authentication, business logic, and workspace isolation - MongoDB stores users, tasks, and workspace relationships - Novu handles notification workflows and delivery - Backend is deployed on AWS EC2 with environment-based configuration and process management

Special focus was given to workspace isolation to ensure users only access relevant data within their own environment.

Challenges

- Designing a secure multi-workspace architecture - Implementing reliable JWT-based authentication - Integrating real-time notification workflows using Novu - Managing complex frontend state across multiple features - Deploying and configuring backend services on AWS

───────────────────────────────────────────────────────

Solutions

- Implemented strict workspace-based validation in backend APIs - Used JWT with controlled expiration and secure password hashing - Integrated Novu workflows for scalable notifications - Used Zustand for efficient global state management - Deployed backend on AWS EC2 with proper environment variables and process handling

Outcome

The result is a scalable, production-ready task management system deployed on cloud infrastructure, with strong focus on user experience, security, and real-time interaction.
