Worked on the JetBrains/Exposed repository to address a persistent migration test failure specific to Windows environments. Focused on stabilizing the test suite by normalizing file path handling, ensuring platform independence and eliminating flakiness in continuous integration pipelines. This effort improved cross-platform consistency and increased trust in automated testing, directly enhancing CI/CD reliability. The work involved Kotlin for test logic and leveraged skills in testing and CI/CD processes. No new features were introduced during this period, as the primary objective was to resolve the bug and accelerate validation, ultimately contributing to faster release readiness and higher build quality for the project.
