Worked on enhancing the Finch Flight software by implementing a checksum-based data integrity validation within the get_id function. Using C programming and embedded systems expertise, the developer introduced a mechanism that verifies incoming data against an expected checksum before allowing further processing. This approach prevents corrupted data from propagating through the ADCS data path, thereby reducing the risk of downstream errors and supporting safer flight operations. All changes were made in the utat-ss/finch-flight-software repository, with careful attention to code quality and traceability through clear commit messages and signed-off contributions, demonstrating a methodical approach to reliability and maintainability.
