Justin Balbuena developed and enhanced full-stack features across the thriftuni and condo-rentals repositories, focusing on robust listing workflows, secure authentication, and real-time data presentation. He implemented end-to-end item listing with image uploads using React Native, TypeScript, and cloud storage integrations such as Firebase and Supabase, ensuring persistent and scalable data handling. Justin stabilized authentication flows with Google Sign-In and resolved complex merge conflicts to maintain codebase integrity. He expanded test coverage with unit and mutation tests, improved UI components, and enabled dynamic home page listings. His work demonstrated depth in backend API design, frontend development, and repository maintenance practices.
April 2025: Delivered end-to-end Item Listing with cloud-backed images, stabilized authentication, expanded testing/QA for listings, and added real-time home-page condo listings while cleaning up dependencies.

March 2025 performance summary focused on delivering UX enhancements, secure authentication, and stack stability across two repositories. In upright thriftuni project, delivered a ProductImages component to replace the ImageCarousel on listing pages, improving product image presentation, styling, and cleaning up unused components. Implemented dynamic routing for product listings and added a dedicated individual listing page featuring seller information and location, along with enhanced product cards and updated mock data. Performed dependency maintenance to align Babel/Expo/React Native packages and resolved merge conflicts, refreshing yarn.lock to ensure a stable build. In condo-rentals, implemented Google Sign-In flow via Expo on the frontend with Supabase authentication integration, including creating a sign-in component and handling ID token exchange. Also established a Supabase client on the backend to support authentication flows and cross-team access. These changes collectively improve user trust and conversion potential, reduce support friction, and streamline multi-team collaboration while showcasing modern React Native, Expo, and backend-as-a-service capabilities.
