Worked on transformerlab-app and transformerlab-api, delivering five features and one bug fix focused on Windows compatibility and GPU handling. Implemented Windows environment readiness and robust log file watching using chokidar, improving build reliability and developer experience. Enhanced the user interface by adding Windows and NVIDIA visual indicators to clarify platform and GPU context. Updated API documentation to specify GPU requirements for training and inference across Linux, WSL2, and macOS environments. Addressed multi-GPU information retrieval on Windows with improved decoding and error handling. Utilized JavaScript, TypeScript, and React, applying skills in backend development, cross-platform support, and system configuration.
