What do you usually do in your professional activity at your current job?

In my professional activity at my current job, I usually develop server-side logic on Node.js, including:

• Designing and implementing REST APIs
• Working with databases (e.g., MongoDB, PostgreSQL)
• Optimizing application performance and scalability
• Writing unit and integration tests
• Implementing authentication and authorization systems
• Debugging and monitoring applications

I also participate in team discussions, code reviews, and support existing functionality.
