Worked on the tenstorrent/tt-umd repository to enhance system stability and cross-architecture robustness in C++. Focused on core development by addressing a critical bug that caused crashes when querying grid sizes on non-grid-arranged cores, such as ETH. The solution involved returning a safe default value of (0,0) for these cases, which prevents runtime failures and improves reliability across diverse core layouts. This targeted bug fix not only resolved a long-standing crash vector but also laid the foundation for future improvements in grid management. Demonstrated strong skills in bug fixing and system stability, contributing to more maintainable and robust code.
