Worked on enhancing the reliability of radareorg/radare2 by focusing on assembly numerical operations, specifically addressing error handling within the r_num_math component. Applied C programming and software refactoring skills to restructure error reporting, resulting in clearer user-facing messages and safer input validation. This effort targeted a persistent bug related to invalid inputs in assembly math workflows, reducing user confusion and improving overall robustness. No new features were introduced during this period, as the primary goal was to stabilize existing functionality. Demonstrated disciplined commit practices and a strong emphasis on robust error handling, contributing to a more maintainable codebase.
