Do you mainly write code or check it as part of your work?

The balance between writing code and testing it as a programmer depends on the role and stage of the project. Usually:

• In the early stages of development, more time is spent on writing code — implementing new features and modules.
• As the project grows and approaches release, the proportion of testing increases — code reviews, testing, bug fixing.

Personally, I try to combine both processes: write quality code from the start and regularly conduct reviews to maintain a high level of quality and reduce the number of errors.
