Dec 1, 2025Month: 2025-12 | Repository: hei-school/hei-admin-api | Focus: reliability, data integrity, and CI stability. Delivered feature: CI Build/Test Stability Improvement by increasing JVM stack size to prevent stack overflow during builds and tests, strengthening CI reliability. Major bugs fixed: data integrity fixes around student status handling and unpaid/overdue fees, including (1) suspending student with overdue fees transaction error, (2) excluding disabled student fees status update to LATE, and (3) marking suspended students as MISSING during event participant initialization. Impact: improved accuracy of student records, reduced risk of incorrect status transitions, and more stable CI pipelines, enabling faster, safer deployments. Technologies/skills demonstrated: Java/JVM tuning, CI/CD optimization, transactional data integrity, edge-case handling in initialization logic, and clear commit hygiene.
