Worked on the lvgl/lvgl repository to enhance build reliability for the Ebike Demo by addressing a critical issue with the lvgl.h include path. Applied expertise in C programming and embedded systems to correct conditional compilation logic and standardize include paths for generated font and image assets. This technical approach reduced compile-time errors and improved cross-demo build consistency, enabling faster development iterations and more reliable releases. Focused on build system hygiene by improving include-path validation and ensuring cross-file consistency, which minimized manual debugging and decreased CI failures. The work demonstrated a methodical approach to maintaining robust build systems in embedded C environments.
