PROFILE
Zhichao Li
Worked on the microsoft/vscode repository, delivering features and fixes across language tooling, terminal UX, privacy, and telemetry. Enhanced LanguageModelToolResult structures with richer metadata and type safety using TypeScript, improving reliability for downstream integrations. Improved the integrated terminal’s mouse wheel zoom by refining event handling and font scaling for better accessibility. Addressed diff output reliability and git-export compatibility, and introduced privacy-focused file handling with configuration management. Stabilized OpenTelemetry integration by normalizing GenAI message schemas and unifying analytics data in SQLite. Demonstrated depth in full stack development, API design, and event-driven architecture, consistently focusing on maintainability and robust user-facing improvements.

Feb 1, 2026February 2026: Privacy-focused improvements and upload consistency for microsoft/vscode. Key changes include introducing a file size limit for reading files and defaulting repository info capture to false to improve privacy and performance in chat sessions; and reverting the upload limit to 1 MB to restore consistency across the app. These updates reduce data exposure, enhance performance in chat-driven features, and minimize user-facing upload issues.
