Do you work only on the frontend or also on the backend?

Although my main specialization is frontend, I also have experience working with backend, which helps me better understand the full architecture of the application and the interaction between the client and server.

For example, I can write REST API on Node.js or set up frontend-backend interaction via AJAX/Fetch, which allows for faster error detection and correction, as well as performance optimization.

This interdisciplinary approach improves product quality and accelerates development, as I can independently implement or test functionality on both sides.
