What major projects based on Node.js have you implemented or participated in developing?

Typically, Node.js interview questions expect you to talk about projects where you applied server-side development, working with APIs, databases, and asynchronous programming.

Examples of major projects might include:

• Developing RESTful APIs for an online store using Express.js and MongoDB.
• Creating real-time systems (chat, notifications) with Socket.io.
• Microservice architecture for processing payments or analytics.
• Integration with external services (e.g., payment gateways or CRM).

If you have experience, describe specific tasks, technologies, and your contributions. For example:

"I participated in developing the backend for an e-commerce platform using Node.js with Express and PostgreSQL. I implemented an authentication module and integrated with the Stripe payment system, ensuring asynchronous task processing via RabbitMQ."

If you do not have experience, it's better to be honest and talk about educational projects or open-source contributions.
