What professional fields or directions would you like to deepen or develop in your career?

Professional development in Node.js can focus on several areas:

• Server application and API development — studying REST, GraphQL architectures, microservices, performance optimization.
• Working with databases — integration with SQL and NoSQL, query optimization, using ORM/ODM.
• Application security — authentication, authorization, protection against common vulnerabilities.
• DevOps and automation — setting up CI/CD, containerization (Docker), orchestration (Kubernetes).
• Real-time application implementation — WebSocket, Socket.IO.
• Testing and code quality — writing unit, integration, e2e tests.

The choice depends on interests and goals, for example, focusing on backend development with an emphasis on scalability and security, or on automation processes and DevOps.
