This project is a fullstack e-commerce web application built using Next.js (React + TypeScript) for the frontend and Nest.js for the backend.

The system includes complete product management, shopping cart, user authentication, and order processing features.

The backend is developed using Node.js with Nest.js, integrated with PostgreSQL via Prisma ORM for efficient data handling.
Frontend design uses Tailwind CSS and Shadcn UI to create a clean, responsive interface with a modern shopping experience.

As part of QA, I performed manual and automation testing to ensure functionality and performance stability, including:

API testing using Postman

Unit & integration tests with Jest

UI regression tests

Bug tracking and test reporting documentation

Tech Stack:

Frontend: Next.js (React.js, TypeScript), Tailwind CSS, Shadcn UI

Backend: Nest.js, Prisma ORM, Node.js

Database: PostgreSQL

Testing: Postman, Jest, Selenium

Outcome:
Delivered a stable, scalable e-commerce web platform that passed all QA validations and achieved smooth deployment with minimal post-release issues.
