Worked on the bcgov/EDUC-GRAD-STUDENT-API repository to enhance graduation workflow stability and test reliability. Developed updates to the graduation student status logic, ensuring students are accurately marked as current based on summer collection criteria. Introduced regression tests and stabilized course-related test data by adding a course level, adjusting examinable end dates, and updating test cases to reflect valid future ranges. These improvements reduced flaky tests and improved continuous integration feedback. Leveraged Java, Spring Framework, and JUnit to strengthen backend data integrity and eligibility processing, focusing on robust unit testing and fixture management to support reliable graduation processing workflows.
