Worked on the better-auth/better-auth repository to enhance the reliability of authentication flows by refactoring the SSO provider retrieval process. Focused on stabilizing enterprise onboarding, the developer centralized SSO logic by introducing a shared helper in the spMetadata module, ensuring that default SSO providers are correctly resolved even when not persisted in the database. This approach reduced runtime errors during login and improved maintainability by minimizing the risk of future regressions. The work was implemented using TypeScript and full stack development skills, with an emphasis on robust API development to support seamless authentication experiences for enterprise users.
