Worked on documentation and backend improvements across two open-source projects. In the usememos/dotcom repository, focused on enhancing onboarding and discoverability by authoring comprehensive Markdown documentation for the MCP Server for Memos, linking to its GitHub repository and clarifying integration points without altering code, thereby maintaining system stability. Later, contributed to DIYgod/RSSHub by addressing a bug affecting VXNA feed published dates, implementing a targeted TypeScript parsing fix to improve data accuracy and reliability for subscribers. Demonstrated skills in documentation, TypeScript, and backend development, with a focus on clear, maintainable changes that support both user experience and data quality.
