Hanada developed and maintained Windows package definitions for the qishibo/winget-pkgs and telegramdesktop/winget-pkgs repositories, focusing on installer configuration and package management using YAML. Over two months, Hanada updated the Adobe Acrobat Reader 64-bit package to version 24.004.20243, refining installer metadata and locale information to support reliable enterprise deployments. For TeraTerm 5.5.0, Hanada delivered cross-architecture binaries, enhanced localization, and introduced new SSH2 key exchange and serial port macro features. The work demonstrated a methodical approach to YAML development, ensuring that package updates aligned with Winget workflows and improved deployment consistency for end users and enterprise environments.
