During February 2026, Emir Rexhepi focused on backend development for the gitroomhq/postiz-app repository, addressing a persistent issue with file uploads via the Upload-from-URL endpoint. Emir implemented a solution in TypeScript that derives and preserves correct file extensions by analyzing the Content-Type header of the response, with a fallback to the URL when necessary. This approach eliminated cases where files were saved without extensions, improving asset management and supporting downstream automation. Emir’s work in API development enhanced the reliability and usability of file handling within the application, reducing manual intervention and ensuring more consistent file processing for end users.
