PROFILE

Dmytrii Puzyr

Worked on feature flag management for the DataDog/dd-sdk-ios and DataDog/dd-sdk-android repositories, focusing on reliable flag retrieval, evaluation tracking, and internal API improvements. Delivered enhancements to both iOS and Android SDKs by refactoring core APIs, introducing type-safe flag parsing, and expanding test coverage to reduce flakiness and improve maintainability. Leveraged Kotlin and Swift to implement robust error handling, improved logging, and code quality measures such as linting and refactoring. The work established a foundation for future external-facing features, stabilized flag handling in React Native integrations, and enabled safer, faster iteration by emphasizing testability and clear software architecture throughout.
