Worked on the Hopin-inc/civicship-portal repository to enhance the reliability of the reservation system by addressing a critical bug affecting slot availability. Focused on frontend development using React, JavaScript, and TypeScript, the work involved ensuring that specific reservation slots were correctly recognized as reservable by updating the slot management logic. This fix allowed users to book across activity slots and time slot lists without encountering errors caused by mislabeling, directly improving the booking experience and reducing potential revenue loss. The solution laid the foundation for more robust slot management and supported future enhancements to the reservation flow within the application.
