Have you participated in backend system development within a team or independently?

Yes, I have experience developing backend systems both in a team and independently. In team projects, I interacted with frontend developers, testers, and managers, using version control systems (Git) and collaboration tools (e.g., Jira, Slack). When working independently, I was fully responsible for the architecture, implementation, and deployment of the service on Node.js, including server and database setup.

Example of a simple Node.js server using Express:

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

app.get('/', (req, res) => {
  res.send('Hello World!');
});

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