Worked on improving cross-platform test reliability for the dotnet/interactive repository by addressing inconsistencies in line endings across different operating systems. Focused on stabilizing the test suite, the developer implemented a ReplaceLineEndings helper in C# to normalize outputs, ensuring that tests produce consistent results on Windows, macOS, and Linux. This technical approach targeted flaky tests caused by OS-specific discrepancies, directly reducing CI flakiness and accelerating pull request validation cycles. Leveraging skills in C# programming, test automation, and unit testing, the work enhanced the reliability of automated testing workflows and contributed to faster, more dependable feedback for ongoing development efforts.
