Case Study
Objective
Build a full-stack authentication system using the MERN stack, implementing secure user registration, login, and protected routes to demonstrate production-ready authentication flows.
Process
I developed a Node.js and Express backend connected to MongoDB, implementing JWT-based authentication and bcrypt password hashing for security.
On the frontend, I used React to create a clean user interface with protected routes and session handling. I structured the application to separate concerns between authentication logic, API communication, and UI state management.
The system includes token validation, route protection, and a simple dashboard to simulate a real-world authenticated user experience.
Outcome
This project demonstrates my ability to build secure, production-ready backend systems and connect them seamlessly to modern frontend applications.
It reinforced my understanding of authentication flows, API design, and full-stack architecture, while serving as a strong foundation for scalable SaaS products.
