PROFILE

Dave Mcalpine

Worked on the Khan/wonder-blocks repository to enhance and modernize the BirthdayPicker component, focusing on robust date handling and technical debt reduction. Addressed edge cases near month boundaries by introducing a useLastDayOfMonth prop and consolidating monthYearOnly logic, which improved reliability and reduced misconfiguration risk. Migrated the component’s date logic from moment.js to the Temporal polyfill, removing deprecated dependencies and updating related documentation, Storybook, and unit tests. Leveraged React, TypeScript, and JavaScript to deliver maintainable, well-tested features that align with product goals for accurate date-based UI behavior, ultimately strengthening both developer experience and long-term code quality.
