During October 2025, Ilsang contributed to the mdn/rari repository by enhancing the Rari CLI to display the server port and log the server address at startup. This feature, implemented in Rust, focused on improving user feedback and streamlining troubleshooting by providing immediate visibility into server binding details. Ilsang applied skills in CLI development and server configuration, ensuring that operators could quickly diagnose startup issues without additional steps. The work was delivered as a single, targeted commit, reflecting a focused engineering approach. While the scope was limited to one feature, the solution addressed a clear operational need for end users.
