Refined key features by including dynamic product browsing, checkout process, and cart functionality. Implemented code splitting in React to optimize front-end performance, improving user experience by reducing initial page load time.Integrated Stripe for secure payment processing, managing payment intents and webhooks through Express on the server side. On the front end, Utilized Stripe Elements to deliver a smooth and user-friendly checkout experience.

Developed and integrated RESTful APIs, efficiently sourced and processed server-side data using Node.js and Express for the backend, with MongoDB as the database and Mongoose for data modeling. Also implemented asynchronous operations and load balancing to ensure high yield and scalability.Managed database interactions and handled user authentication (OAuth/JWT) using MongoDB with Mongoose, ensuring secure data storage and efficient query handling. Integrated OAuth-based authentication for third-party login services and jsonwebtoken (JWT) for secure, token-based authentication. Implemented best practices for user safety, including encryption of sensitive data, secure password hashing using bcrypt, and implementing token expiration.Contributed to the React/Tailwind Front-End by building reusable components in React to manage state and UI rendering, ensuring code maintainability and scalability. Applied Tailwind CSS utility classes to rapidly create responsive layouts without inflating the codebase.
