Which part of development do you prefer — the user interface or the server side?

I prefer to work on the server side, as I am more interested in handling data processing logic, optimizing performance, and interacting with databases. In C/C++, this often involves writing efficient and reliable code that is responsible for business logic and system resource management.

However, the user interface is also important, especially when it comes to ensuring application usability and responsiveness. Overall, the choice depends on the project and tasks, but the server side seems more attractive from a technical depth perspective.
