Besides like trello asana redmine or the millions of less-complicated competitors? You literally have developers work on their own modules directly from the spec or work directly with the product owner. You track their work by looking at their commits. You check their progress by looking at how the preview build / staging looks. No overhead of having developers flesh out an entire issue/story (plus sub-issues) and then move it column-to-column across the entire Kanban board. Tracking sub-issues is like counting half-pennies instead of rounding up.
