Worked on the trunk-io/analytics-cli repository to address a bug affecting test case reference resolution in Rust-based back end systems. Focused on improving the reliability of test artifact mapping by implementing logic that prioritizes the 'file' field over 'filepath' when both are present, with a fallback to 'filepath' if necessary. This approach reduced misreferences in test reports and stabilized test execution, directly supporting ongoing quality assurance and continuous integration goals. The solution leveraged Rust and back end development skills to enhance the accuracy of test case file references, ultimately decreasing test failures and increasing developer confidence in test artifacts.
