Justin Rivera developed core marketplace features for the uprm-inso4101-2024-2025-s2/semester-project--uprm-online-marketplace repository, focusing on migrating listing data from in-memory storage to Firebase Firestore. He implemented asynchronous data retrieval using Dart and Flutter, introducing real-time updates and mapping Firestore documents to domain objects through factory constructors. Justin enhanced data integrity by linking listings to user IDs and enabling user-specific features such as ownership and favorites across the UI. By replacing dummy data with live Firestore integration and updating unit tests for asynchronous operations, he improved scalability, data consistency, and personalized user experiences without addressing major bugs during this period.
April 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.

March 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.
