Over a two-month period, contributed to the zephyrproject-rtos repositories by delivering two core features focused on embedded systems. Developed touchscreen input support for the STM32MP135F_DK board in zephyr-testing, integrating LVGL pointer input via I2C and customizing the device tree to enable robust UI interaction on embedded LCD hardware. Later, implemented an Ethernet HAL RMII clock configuration abstraction in hal_stm32, making the reference clock handling instance-agnostic and simplifying upper-layer logic for multi-instance Ethernet support. Work demonstrated proficiency in C programming, Zephyr RTOS, and hardware abstraction layers, with an emphasis on maintainability and scalable board-level integration.
