April 2025 – Center-Stage: Delivered key UX improvements and data-flow enhancements focused on onboarding, class management, and content discovery. Authentication and signup UI polish reduced friction with password confirmation and consistent styling across login and profile/settings. Immediately after class creation, teachers can be linked to the class, ensuring correct teacher-class associations. The Resources module now features distinct tabs for videos and articles, with a backend article search endpoint and a UI search bar to support filter-by-name queries. These changes collectively improve onboarding conversion, data integrity, and content accessibility, while showcasing strong frontend craftsmanship and backend support.

March 2025: Delivered a QR Code Based Check-In System for Center-Stage, integrating a QRCode component into teacher class and event modals with import refactors for cleaner usage. Implemented idempotent check-ins by adding a GET endpoint to verify existing enrollments and switching event check-ins to PUT for safer, idempotent updates. Added tests to prevent duplicate check-ins by ensuring only a single POST occurs during QR code-based check-in. These changes streamline attendance, improve data integrity, and reduce support overhead for instructors and administrators.
