Justin
Justin Rivera developed Firestore-backed listing features for the uprm-inso4101-2024-2025-s2/semester-project--uprm-online-marketplace repository, focusing on real-time data integration and user-centric functionality. He migrated listing storage from in-memory to Cloud Firestore, implementing asynchronous data retrieval and mapping Firestore documents to Dart domain objects. Justin established user ownership by linking listings to creator IDs and enabled real-time updates for favorites and ownership status across the Flutter UI. His work replaced all dummy data with live Firestore sources, improving data consistency and enabling personalized experiences. The project leveraged Dart, Firebase, and state management to support scalable, testable mobile marketplace features.

Apr 1, 2025April 2025: Completed migration of listings to Firestore as the primary data source, establishing user ownership and isFavorite support across the UI. Listings creation now saves under the active user's ID, and the UI components (HouseTile, MyListings, InactiveListings, FavoritesPage) consume real-time Firestore data. Replaced all dummy data with live Firestore data to enable real-time updates and accurate ownership.

Mar 1, 2025March 2025: Implemented Firebase Firestore integration for listing data, replacing in-memory retrieval with asynchronous fetchListing and fetchListings. Added Lodging factory constructor to map Firestore documents to Lodging objects. Updated tests to reflect async Firebase operations. No major bugs fixed this month; minor test adjustments were made. This work improves data consistency, reduces data retrieval latency, and enables scalable listing handling for the marketplace.
