Worked on enhancing test automation and performance monitoring for the bugsnag-js and bugsnag-android-performance repositories. Focused on upgrading Appium from version 1.22 to 2.19, which improved compatibility and enabled new testing features across CI/CD pipelines. Introduced new benchmarking configurations for Android app activities and packages, providing deeper performance insights. Addressed configuration management by removing duplicate CLI arguments in React Native test setups, reducing the risk of misconfigurations and streamlining the testing process. Utilized Kotlin, YAML, and INI to implement these changes, resulting in more reliable automated testing, faster feedback cycles, and improved visibility into cross-platform application performance.
