Matteo Baglini focused on improving search reliability and user experience across the zextras/carbonio-mailbox and zextras/carbonio-mails-ui repositories. He addressed two complex bugs by refining how multi-word phrase queries are quoted, ensuring accurate phrase matching in both backend and frontend search functionalities. Using Java, TypeScript, and Lucene, Matteo implemented targeted fixes and refactored code for better readability and maintainability. He also expanded unit test coverage to enhance CI reliability and prevent regressions. By aligning backend and frontend changes under a common issue, Matteo delivered consistent search behavior, demonstrating depth in both backend development and frontend integration within a short timeframe.
