Over a two-month period, contributed to both 86Box/86Box and ggml-org/llama.cpp by delivering targeted feature enhancements and stability improvements. Focused on C programming and device driver development, addressed memory management and input reliability in the mouse microtouch driver, correcting baud rate handling and refining detection logic to improve maintainability and safety. Enhanced code quality through refactoring and safer string handling, while documenting future driver enhancements. In the llama.cpp repository, implemented a React-based Enter-to-Send chat setting, improving user experience and accessibility across devices. Demonstrated a methodical approach to embedded systems, front end development, and system programming in both projects.
