Developed a synthetic flight data framework for the masa-umich/Rocket-Avionics repository to validate autosequence logic across various rocket flight phases, with particular attention to edge-case scenarios. Leveraged C programming and embedded systems expertise to expand test coverage and automate data-driven validation, accelerating the verification cycle for avionics detection algorithms. Addressed minor issues in the test infrastructure by correcting utility typos, which improved the reliability of continuous integration and reduced flaky test results. This work enhanced the robustness and traceability of the avionics software, strengthening overall software quality through improved test data generation and comprehensive validation of critical flight logic.
