Worked on packaging, installer, and localization enhancements for the OreNoFusen desktop application, focusing on distribution readiness and regional usability across the vedantmgoyal9/winget-pkgs and zed-industries/winget-pkgs repositories. Leveraged YAML configuration and manifest creation to standardize versioning, metadata, and locale files, enabling smoother deployments and improved accessibility for multiple release lines. Delivered new features such as instant editing, WYSIWYG rich text, and multi-window support for sticky notes, while maintaining robust package management and software distribution practices. Prioritized stabilization and quality of packaging artifacts, reducing installation failures and localization gaps without explicit bug fixes during the development period.
