Worked on enhancing the reliability of the Kanban and recurring tasks workflow in the go-vikunja/vikunja repository by addressing a bug affecting date handling for repeating tasks. Focused on ensuring that start, end, and due dates were correctly updated when tasks transitioned to the done bucket, thereby improving task planning accuracy and reducing manual corrections. Applied Go for back end development and leveraged test-driven development practices to validate the fix, adding comprehensive tests to prevent future regressions. Emphasized maintainability through clear commit messages and issue traceability, ultimately contributing to more dependable scheduling and reporting for users of the system.
