Worked on backend reliability for gitroomhq/postiz-app by addressing a file handling issue in the Upload-from-URL endpoint. The solution involved using TypeScript to derive and preserve correct file extensions, extracting them from the response Content-Type header or falling back to the URL when necessary. This approach eliminated cases where files were saved without extensions, streamlining asset management and improving usability for downstream automation. The work focused on API development and backend development, ensuring that files are consistently handled and reducing the need for manual intervention. The fix enhanced the robustness of file uploads and contributed to smoother operational workflows.
