PROFILE

Kayoon Koh

Worked on the Purdue-Artificial-Intelligence-in-Music/Evaluator-code repository, delivering GPU-accelerated video analysis and robust processing workflows for Android and React Native. Developed features using Kotlin, JavaScript, and TensorFlow Lite, including modular detector relocation, unified video processing, and user-driven save or delete options with cache-based storage. Focused on error handling and state management, implementing cancellation support across both native and React Native layers to ensure predictable cleanup and prevent data loss. Refactored modules for maintainability and improved user experience by streamlining backend flows, enhancing performance, and ensuring that cancellation and error states were consistently managed throughout the application.
