At which stage of professional activity is it more common to combine team management with performing software tasks — as a team lead or a tech lead?

Most often, managing a team while performing software tasks is associated with the role of a team lead. The team lead is responsible for both technical guidance and organizing the team's work, so they need to write code, participate in development, and coordinate colleagues simultaneously.

A tech lead, on the other hand, usually focuses on architecture, technical solutions, and strategic product development, dedicating less time to direct coding and people management. In large teams, a tech lead may not be directly involved in management but focus on technical aspects.
