Worked on improving codebase quality and platform stability across two major open-source repositories. In go-gitea/gitea, addressed repository hygiene by updating the .gitignore to exclude the /.pnpm-store directory, which reduced large, noisy diffs and streamlined pull request reviews. In lvgl/lvgl, focused on embedded systems by implementing an ARM MVE Compatibility Guard using C, introducing a pre-check to prevent inclusion of MVE-specific files on unsupported platforms. This approach mitigated runtime errors and centralized conditional compilation logic, enhancing maintainability. Demonstrated proficiency in C programming, low-level development, and version control while delivering targeted solutions to reduce defects and improve developer experience.
