How was code review and approval conducted within the team before integration?

The team usually uses a version control system (e.g., Git) with a pull request (PR) process. A developer creates a separate branch, makes changes, and opens a PR. Other team members conduct code reviews, checking code quality, adherence to standards, absence of errors, and potential bugs. After the PR is approved by a responsible person or team, the changes are merged into the main branch and undergo integration testing. This process helps maintain code quality and prevent errors from reaching the release.
