Worked on enhancing PHP Enum support in serialization for the getsentry/sentry-php repository, focusing on accurate representation of enum variants during data serialization. Developed a feature that updates the serializer logic to include both the enum class and specific variant names in the serialized output, ensuring precise handling of PHP Enums. The implementation involved modifying AbstractSerializer.php to detect and process Enum types, as well as introducing comprehensive unit tests in AbstractSerializerTest.php to validate the new behavior. Utilized PHP and back end development skills with an emphasis on serialization and Enums, delivering a targeted improvement to the repository’s data handling capabilities.
