Worked on backend stability for the PlakarKorp/plakar repository, focusing on refining the logout flow to enhance user experience and session management. Addressed a key bug by implementing idempotent logout behavior in Go, ensuring that repeated logout attempts succeed without generating unnecessary error messages. This approach improved the resilience of session handling and reduced confusion for users, while maintaining compatibility with the existing authentication workflow. The solution involved handling the ErrNotLoggedIn case gracefully within the API, simplifying edge-case management and reducing support overhead. The work demonstrated attention to backend development best practices and careful consideration of user-facing interactions.
