E-commerce Platform Development

The E-Commerce Platform is a robust and scalable solution designed to support online retail operations. It facilitates a seamless shopping experience for users, encompassing features such as product listings, user authentication, shopping cart management, order processing, and real-time inventory updates. The platform leverages Node.js, Express.js, API creation, MongoDB for database management, and SonarQube for code quality assurance.



My Role and Contributions

As a developer on this project, I was responsible for the end-to-end backend development and system optimization. My key contributions included:



Backend Development:



Node.js & Express.js: Designed and implemented the backend using Node.js and Express.js, ensuring a robust and scalable architecture to handle high volumes of transactions.

RESTful API Creation: Developed secure and efficient APIs for user registration, product management, order processing, and payment integration.

Database Management:



MongoDB & Mongoose: Designed the database schema and managed data storage using MongoDB. Utilized Mongoose for efficient data modeling and interaction.

Implemented features like product catalog, user profiles, order history, and real-time inventory management.

Real-Time Features:



Implemented real-time inventory updates to reflect stock changes as orders are placed and processed.

Integrated real-time notifications for order status updates and promotional alerts.

Error Resolution and Code Quality:



SonarQube Integration: Integrated SonarQube for continuous code quality checks and static analysis.

Resolved complex code issues identified by SonarQube, including code smells, bugs, and vulnerabilities, ensuring high code quality and security.

Performance Optimization:



Optimized API performance to handle a large number of concurrent users and transactions efficiently.

Conducted load testing and optimized database queries to ensure the system could handle peak traffic times, such as during sales events.

Security Enhancements:



Implemented robust authentication mechanisms using JWT (JSON Web Tokens) for secure user sessions and transaction processes.

Ensured data validation and encryption to protect sensitive user and payment information.
