Developed and delivered a native file manager integration for the GopeedLab/gopeed repository, enabling users to open directories and files directly in their operating system’s file manager across Windows, macOS, and Linux. This feature included support for third-party file managers, aligning file access with OS conventions to streamline user workflows and reduce context switching. The work demonstrated cross-platform development expertise using Dart and Flutter, with a focus on OS-level file-system interaction and seamless integration. The implementation was commit-driven and addressed user experience improvements, though no major bugs were reported or fixed during this period, reflecting a targeted and stable feature delivery.
