Worked on stability and quality improvements across open-source repositories, focusing on C and Python projects. In the openssl/openssl repository, addressed memory safety and test determinism by refining Argon2 test skipping logic and preventing use-after-free errors in the EVP test suite, enhancing reliability for cryptographic test paths. Applied strong C programming and memory management skills to reduce flaky test runs and improve CI outcomes. Later, contributed to microsoft/lisa by improving Python packaging hygiene, adding an __init__.py file to the examples directory to satisfy linting requirements and ensure consistent package recognition, thereby supporting better code quality and downstream packaging reliability.
