How long and in what projects have you worked with Node.js, and what tasks did you solve with it?

I have worked with Node.js for about 2 years, mainly on web application and API development projects. My main tasks included creating RESTful services, handling requests, and working with databases (MongoDB, PostgreSQL). I also used Node.js for writing server-side logic, user authentication, and integrating with external services. For example, I implemented a user management system with JWT and middleware for data validation.
