• Technical leadership:

  • Conducts code reviews, monitors code quality.

• Mentoring:

  • Trains and supports less experienced colleagues.
  • Shares knowledge and experience.

• Planning and estimation:

  • Participates in task estimation and sprint planning.
  • Helps break down complex tasks into subtasks.

• Responsibility for results:
