PROFILE
Derek Cho
Worked on the pennlabs/penn-clubs repository, delivering targeted improvements to both frontend and backend systems over a two-month period. Addressed a persistent infinite loading issue on the Applications page by implementing a null and empty state in React, enhancing user experience for clubs without applications. Developed features to surface officer status in the frontend and optimized membership queries by introducing a composite database index using Django and Python. Modularized event fetching logic and filtered out past events to improve homepage relevance. Focused on maintainability, operational reliability, and clear data contracts, leveraging JavaScript, TypeScript, and database management skills throughout the work.
