Worked on enhancing localization and domain configuration across two repositories, AppFlowy-IO/AppFlowy and is-a-dev/register. Improved the Korean user experience in AppFlowy by updating and refining ko-KR translation strings, aligning with internationalization goals and ensuring readiness for broader global adoption. In is-a-dev/register, delivered a JSON-based domain configuration for hoyaaaa.is-a.dev, incorporating owner metadata, DNS records, and an owner email field to support provenance and provisioning workflows. Utilized skills in internationalization, localization, configuration management, and data modeling, with a technical focus on JSON and YAML. The work emphasized maintainability, clear commit practices, and foundational support for future automation.
