In my last project, we used the following technology stack: - **Front-end**: React.js is used to build the user interface, Redux manages application state, and Sass is used for style writing. - **Back-end**: Node.js and Express.js build RESTful APIs, MongoDB is used as a database, and Mongoose is used as an ODM tool. - **Tools**: Webpack is used to package front-end resources, Babel is used for ES6+ syntax conversion, and Jest and Enzyme are used for testing. - **Deployment**: Docker is used for containerized deployment, Nginx is used as a reverse proxy server, and AWS EC2 provides computing resources. Through these technologies, we successfully developed and deployed a high-performance and scalable web application.
