We are starting agency at Upwork, called Chenix, based in Ukraine, Cherkasy.
I, as a project manager and scrum master have used Trello boards for scrum and task management. But Jira looks much more interesting for project management. Now in Jira Software app I have various different entities, like Projects, Workflows, Backlog, Issues, Issue types, Sprints and etc. That's amazing!
I hope to find Jira Software useful for scrum management.
