Worked on the better-auth/better-auth repository to enhance the organization invitation workflow, focusing on backend stability and user experience. Addressed a specific edge case where re-inviting users to an organization would fail due to existing pending invitations, leading to unnecessary errors and support overhead. Implemented a targeted bug fix in TypeScript that cancels prior pending invitations when a re-invite is issued, ensuring seamless invitation management and reducing friction for end users. Leveraged skills in API development, backend development, and testing to improve the reliability of the invitation process, ultimately supporting a smoother onboarding experience for organizations using the platform.
