Worked on enhancing the API documentation for the tigerbeetle/tigerbeetle repository, focusing on improving clarity and accuracy for developers integrating with the system. Addressed a documentation bug by clarifying that secondary identifiers are associated with transfers rather than accounts, ensuring the API reference aligns with the actual implementation. This update, delivered as a minor documentation patch, aimed to reduce developer confusion and minimize potential support queries. Utilized Markdown for technical writing and documentation, applying attention to detail and clear communication. The work demonstrated a methodical approach to maintaining high-quality documentation, supporting a smoother developer experience and reducing integration risks.
