Eric Petzel enhanced cross-platform RUM feature flag tracking for DataDog’s dd-sdk-ios and dd-sdk-android repositories, focusing on accuracy and maintainability. He refactored the tracking logic to use the variant key rather than the flag value, streamlining evaluations and reducing parsing overhead on both iOS and Android. Working in Swift and Kotlin, Eric updated unit tests to align with the new behavior and performed code formatting cleanups to improve codebase consistency. His work improved the reliability of RUM analytics for product decisions and demonstrated strong skills in Android and iOS development, unit testing, and code quality practices within a collaborative environment.
