Holly Schilling contributed to the customerio-ios repository by delivering infrastructure updates, feature enhancements, and comprehensive documentation over a three-month period. She improved CI/CD workflows by updating GitHub Actions for MacOS 15 compatibility and refactored core components like EventBus and DIGraphShared to strengthen concurrency management and thread safety using Swift. Holly enhanced test reliability by isolating mocks and modernized demo app builds with updated symbol formats and memory safety enforcement. In March, she authored detailed SDK documentation covering deep linking, push notifications, and event tracking, which streamlined onboarding and integration. Her work demonstrated depth in asynchronous programming, dependency injection, and documentation.
