Stella Bailey

Over a twelve-month period, contributed to SEMOSS/semoss-ui by building and refining a wide range of frontend features and comprehensive automated tests. Focused on enhancing UI reliability, the work included implementing type-safe theming, refreshing settings interfaces, and expanding test coverage for visualization, transformation, and renderer components. Leveraged React, TypeScript, and Styled Components to deliver responsive layouts and maintainable code, while employing Jest and React Testing Library to validate rendering, user interactions, and error handling. This approach reduced regression risk, improved CI feedback, and supported safer feature iterations, resulting in a more robust and maintainable user interface for SEMOSS.
