Worked on public-facing features and reliability improvements across the mistralai/cookbook and juicedata/juicefs repositories. Delivered a standardized Human-in-the-Loop (HITL) cookbook by replacing private SDK dependencies with the public mistralai SDK, streamlining installation with TypeScript support, and clarifying documentation for accessibility. Refactored the cookbook to focus on core recipes and simplified configuration flows. In the JuiceFS SDK, addressed cross-platform compatibility by updating Go-based build and loader mechanics to handle platform-specific library loading, and introduced a new flag to ensure complete filesystem closure on delete, enhancing resource management. Demonstrated strengths in Go, TypeScript, API integration, and technical documentation.
