Can you tell about your participation in projects and your roles there?

In my projects, I usually participated in developing the server-side using Node.js, creating REST APIs, integrating with databases and external services. As a developer, I wrote business logic, configured routing, and ensured error handling.

In some projects, I also acted as a team lead, coordinating the work of a team of several people, distributing tasks, and conducting code reviews. It was important to maintain code quality and adhere to architectural decisions.

For example, in one project, I implemented an authentication and authorization system using JWT, and also integrated services for sending notifications via email and SMS.
