Worked on the TOAST-DOCS/TOAST-Cloud repository to enhance public API documentation, focusing on IAM features and developer onboarding. Over two months, delivered updates that improved readability, completeness, and localization of API documentation, using Markdown and leveraging skills in API documentation and technical writing. Introduced new endpoints for password policy retrieval and token management, while clarifying constraints and field usage for IAM protocols. Added Chinese language support to broaden accessibility and updated project and organization member management guides. The work emphasized clear communication of API changes, maintained documentation quality, and reduced ambiguity for API consumers, supporting a smoother developer experience.
