Worked on hardware enablement and driver development for MediaTek platforms, focusing on GPIO and pin control functionality. In the zephyrproject-rtos/trusted-firmware-a repository, delivered hardware-level GPIO support for the MT8189 platform and resolved a register mapping bug for MT8196, improving reliability and reducing bring-up time. Later, contributed to geerlingguy/linux by implementing device tree bindings and a pinctrl driver for MT8189, enabling robust pin configuration through the Linux kernel’s pinctrl subsystem. Leveraged C and YAML to develop and document device tree bindings, demonstrating expertise in embedded systems, hardware interaction, and Linux kernel development for SoC hardware integration and support.
