Worked on stabilizing the continuous integration process for the aws-amplify/amplify-ui repository by addressing test flakiness in React Native environments. Focused on ensuring deterministic test results, the work involved pinning the Expo SDK to version 51 within the reusable build system and updating both the GitHub Actions workflow and supporting shell scripts. This approach reduced inconsistencies caused by version drift and improved the reliability of automated testing. Leveraged skills in CI/CD, React Native, and testing, with practical use of Shell and YAML to enforce consistent environments. The changes resulted in faster feedback loops and more predictable test outcomes for the project.
