Ethan Kaplan contributed to the MeasureAuthoringTool suite by engineering robust UI and backend features that streamline measure authoring and data management. Working across repositories such as madie-measure and measure-service, he implemented feature-flag-driven UI controls, ownership and locking workflows, and FHIR-based data handling to improve collaboration and data integrity. Ethan applied React and TypeScript to refactor components for maintainability, standardized table and form behaviors, and enhanced error handling and test coverage. His work included backend enhancements in Java and Spring Boot, ensuring reliable versioning and search performance. These efforts resulted in a more stable, user-friendly, and scalable authoring platform.
February 2026: Delivered cross-repo UI enhancements and stability improvements across the Measure authoring suite. Implemented comprehensive UI/UX enhancements and component refactors across Measure UI components (TestCase, MeasureList, Measure Details sidebar, and population criteria sidebar) to improve visual consistency, layout responsiveness, and maintainability. Standardized table header styling across madie-measure, madie-editor, and madie-cql-library, improving readability and visual polish. Fixed a critical bug to preserve metadata (id and profile) during ElementEditor submissions, reducing data-loss risk. Completed lint cleanup and minor refactors to improve code quality and consistency. Demonstrated frontend skills in CSS/JS, component architecture, and cross-repo collaboration, delivering tangible business value: faster feature iteration, more reliable UI, and improved user satisfaction.
