Worked on stabilizing session management within the immutable/ts-immutable-sdk by addressing a critical bug that caused infinite refresh loops following a RefreshTokenError. Applied TypeScript and React skills to implement safeguards that prevent further session refresh attempts after a failed refresh, thereby reducing the risk of cascading errors and improving session reliability for end users. Focused on front end development, the solution ensures that user sessions are less likely to be interrupted by repeated errors or forced restarts. This targeted fix enhanced the robustness of session handling in production environments, contributing to a smoother and more reliable user authentication experience.
