Could you name three areas where you consider yourself less strong and need development?

Naming areas for development is useful for self-improvement. Here are three examples of such areas for a Python developer:

1. Code performance optimization — improving profiling and optimization skills to write more efficient programs.
2. Asynchronous programming — mastering asyncio and other tools for working with asynchrony and concurrency.
3. Testing and code coverage — deepening understanding of writing unit and integration tests, using pytest and other frameworks.

Each of these areas helps to write more quality, reliable, and faster code.
