Blake Chang

Blake Chang contributed to the comp-development/COMP repository by building robust access control and data visualization features, focusing on secure test access and improved event analytics. He implemented a Test Access Rules Engine with both backend logic and an admin UI, ensuring only authorized students could view specific tests, and supported complex scenarios like multi-event enrollments. Blake enhanced the user experience with standardized form validation and interactive mapping of event organizations, leveraging Svelte, TypeScript, and PostgreSQL. His work included careful database migration and seeding management, repository cleanup, and error handling, resulting in a maintainable codebase and more reliable deployment processes.

Apr 1, 2025

April 2025 focused on delivering a robust, scalable test access and visibility solution for COMP, while tightening migration hygiene and UI reliability. Key work included porting and extending the end-to-end Test Access Rules Engine (admin UI for custom access criteria, backend rules evaluation, check_test_access logic, and student-facing visibility) with support for multi-event enrollments and custom fields. This work reduces exposure of tests to unauthorized students and improves data accuracy across events. UI enhancements for test-related file handling (ScanButton import fix and a standardized HTML upload button) improved reliability and developer productivity. Migration Organization Cleanup improved maintainability and reduced deployment risk by aligning migrations with the correct path and removing outdated CLI references.

In March 2025, delivered analytics-enabling features for COMP and improved repository hygiene to support ongoing analytics work. Key deliverables included a new Stats navigation item and route for data visualization, with geocoding and map visualization groundwork for event statistics. Maintained code quality and readiness for migration via initial database migration scaffolding. Conducted repository cleanup by removing outdated Supabase CLI remnants and handling empty/no-op commits to reduce noise and future conflicts. Collectively, these efforts enable faster data-driven decision making and a more maintainable analytics foundation.

February 2025: Delivered key UX improvements and new data visualization features in the COMP repo, focusing on reliable form validation feedback and event organization mapping. Standardized validation messages for date, email, and telephone inputs and updated validation logic to use these messages, improving error clarity and reducing user confusion. Implemented Event Data Visualization: Organizations Mapping page that fetches registered organization addresses, plots them on a map using geocoding services, and enhances the event display with a table of registered organizations. These changes provide immediate business value by reducing submission errors, enabling data-driven event insights, and laying groundwork for future analytics.
