Developed a comprehensive Applicant Verification Backend Test Suite for the ResumeRover/Main repository, focusing on enhancing backend reliability and test coverage. The work involved designing and implementing unit tests in Python to validate blockchain integration, core API endpoints, helper utilities, and mock database functionalities. By simulating oracle logic and leveraging mocking techniques, the suite ensures robust verification workflows and reduces production risk. This approach enables faster QA cycles and lays the groundwork for future automated testing. The project demonstrated strong skills in backend development, API testing, and blockchain integration, contributing to a more maintainable and resilient backend architecture for applicant verification.
