What experience do you have with Node.js? What exactly did you do?

I have experience working with Node.js in several projects:

• Development of REST API: Created server applications using Express.js for handling requests, working with databases (MongoDB, PostgreSQL), authentication, and authorization.
• Implementation of server logic: Wrote business logic, integrated third-party APIs, implemented error handling and logging.
• Working with WebSocket: Used socket.io to implement real-time features in applications, such as chat or real-time data updates.
• Automation and scripts: Wrote Node.js scripts for task automation, file processing, and CI/CD integration.

Example of a simple server on Express.js:

const express = require('express');
const app = express();

app.get('/api/data', (req, res) => {
  res.json({ message: 'Hello from Node.js!' });
});

app.listen(3000, () => {
  console.log('Server started on port 3000');
});

This experience allows me to efficiently create and maintain server-side parts of web applications using Node.js.
