Over six months, Peter Kim delivered seven features to the mbta/screens repository, focusing on admin UI enhancements, audio output improvements, and robust error handling. He implemented configurable push-button audio for bus shelters, a reusable NoData component for elevator screens, and a location column in admin tables, using React, TypeScript, and CSS. His work included backend logic for audio interval management, spell-out interpretation for berth numbers, and offline support for Sentry event caching. Each feature was supported by targeted unit tests and clear commit history, reflecting a methodical approach to maintainability, user experience, and reliability across both frontend and backend systems.

Dec 1, 2024December 2024 — mbta/screens: Delivered Elevator Screens NoData UX Enhancement. Implemented a reusable NoData component and integrated it into the application's component mapping to display a clear empty-state when no relevant data is available on elevator screens. This reduces user confusion, aligns with product UX standards, and creates a scalable pattern for future empty states. No other features or bug fixes were documented for this repository this month.
