Secure Authentication
bcrypt password hashing, express-session management, and connect-flash messaging for login/registration feedback.
The Challenge
Creating a full-featured marketplace platform from scratch that handles user authentication, product listings with image uploads, and a campus-verified trust system, all while following Rational Unified Process (RUP) methodology for structured iterative development with proper documentation and phase deliverables.
The Solution
I built the platform using Node.js with Express 5 and MongoDB/Mongoose for flexible document storage. Authentication uses bcrypt for password hashing with express-session for state management. Image uploads are handled through Multer middleware. The EJS templating engine with express-ejs-layouts provides a clean MVC-like separation. I followed RUP methodology throughout, producing inception, elaboration, and construction phase artifacts.
