What volume of tasks have you had to solve in practice?

The scope of tasks I have encountered in practice ranged from small modules and utilities to more complex components within projects. For example, I implemented business logic for data processing, integration with external APIs, and also optimized application performance. I often worked with collections, data streams, and databases, solving tasks related to data processing and storage. This experience helped me understand the fundamental principles of development and learn how to apply them effectively in real-world conditions.
