Junjia Liu contributed to hackclub/dinosaurs by integrating the Junyali Dino asset, updating both the README and asset catalog to ensure consistent documentation and maintainable asset management. Their work emphasized clear asset naming conventions and repository hygiene, facilitating future asset reuse. On hackclub/site, Junjia updated the moderation team roster by manipulating team.json to reflect new members, roles, and avatar URLs, thereby improving the accuracy and transparency of team representation. Throughout both projects, Junjia applied skills in JSON manipulation, documentation, and data management, delivering targeted feature enhancements with traceable, well-documented changes, though the scope remained focused on incremental improvements.
