It is possible to list more than one "Project Role" for a project. If you have had 2 or more distinct roles on the same project, such as Python developer, Architect, Scrum Master, you can list each of these project roles separately.
Each role should be tagged using tags that describe that role.
When the salespeople export your CV they can decide which of the project roles to include, based on the tags you have added to the project roles.
