Participation in the implementation of a project at some stages or its launch from scratch?

Participation in project implementation at any stage — whether it is planning, development, testing, or deployment — requires understanding the architecture and goals of the project. If you start a project from scratch on Node.js, it is important to:

• Define the project structure and choose appropriate modules.
• Set up the environment and version control system.
• Implement basic functions and APIs.
• Organize error handling and logging.
• Configure automated testing and CI/CD.

An example of a simple server on Node.js using Express:

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

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

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

This approach allows gradually expanding functionality and maintaining code quality.
