During May 2025, Hiba Abbas developed zone-based ride request validation for the ButterWalk repository, focusing on enforcing geofence compliance for pickups and drop-offs. She introduced a Zone class and a ZoneService, integrating real-time zone checks into the RideRequestForm using React Native and TypeScript. Hiba also updated the BuildingService to support location-based validations, laying the groundwork for scalable geofence rules. This feature ensures that ride requests are only accepted within designated areas, improving dispatch reliability and reducing invalid requests. Her work demonstrates a solid understanding of frontend development and geospatial validation, providing a foundation for future geo-enabled features.
