Worked on enhancing the fuzz testing infrastructure for the paritytech/foundry-polkadot repository, focusing on improving the robustness and reliability of test execution. Addressed a critical issue where fuzzing tests could return None for library addresses by introducing deterministic random address generation, thereby preventing panics and ensuring smoother CI runs. Leveraged Rust programming skills alongside expertise in fuzz testing and random number generation to increase code safety and expand fuzzing coverage. The work emphasized software testing best practices, resulting in more stable and reliable test outcomes. No new features were added during this period, but a key bug fix improved overall test stability.
