Developed a custom assert header extension for the zephyrproject-rtos/zephyr-testing repository, focusing on enhancing logging and debugging capabilities within embedded systems. The solution allowed applications to globally override and extend ASSERT macros, enabling interception of log strings at the macro level for more flexible and advanced logging workflows. This approach was implemented in C, leveraging strong debugging skills and aligning with existing logging and shell extension patterns to ensure consistency and maintainability across the codebase. The work addressed the need for customizable assertion handling, supporting easier debugging and integration with established project infrastructure without introducing new bugs during the development period.
