During April 2025, Gabriel Viera developed three user-facing features across the thriftuni and condo-rentals repositories, focusing on API reliability and data-driven property discovery. He implemented a JavaScript-based fuzz testing script to strengthen the thriftuni API by systematically probing listings and sellers endpoints for robustness. In the condo-rentals project, Gabriel built an area-based property listings API using TypeScript and Express.js, introducing area validation, selective field querying, and result limiting to enhance search precision. He also delivered a trusted landlords discovery feature, refactoring the backend data layer and integrating a React Native UI to improve landlord transparency and connectivity for end users.
