Worked on the lvgl/lv_port_linux repository, focusing on enhancing Wayland backend performance and stability for embedded Linux systems. Developed two features in C and C++ that optimized event loop responsiveness by refactoring idle wait logic to use timer-based durations and integrating G2D hardware acceleration through conditional CMake configuration. This enabled more efficient rendering and prepared the system for broader hardware support. Additionally, addressed a timing bug by correcting idle sleep duration calculations, further improving event handling. The work demonstrated a strong grasp of build systems, embedded Linux, and display technologies, delivering targeted improvements to both performance and reliability.
