To improve productivity and better understand backend development, I built a full stack Task Manager application that allows users to register, log in, and manage their personal tasks securely.
The goal was to design a scalable backend with proper authentication, REST APIs, and structured database design.
Tech Stack Used -
React.js (Frontend)
Node.js
Express.js
MongoDB
Mongoose
JWT Authentication
REST APIs
Postman (API Testing)
Backend Architecture -
The backend was built using Express.js with a RESTful structure.
I implemented:
User registration and login APIs
JWT-based authentication
Protected routes using middleware
CRUD APIs for task management
MongoDB schema design using Mongoose
Structured controller and route separation
Each task is associated with a specific user using object references to maintain data integrity.
What I Learned-
Designing secure REST APIs
Implementing authentication and authorization
Maintaining data consistency using MongoDB schemas
Handling backend error responses properly
Debugging real-world API issues
