HODOUR

Universities run on paper, emails, and spreadsheets. Hodour replaces the entire stack: QR code + GPS-verified attendance that eliminates proxy fraud, grade management with weighted calculations and official transcript generation, a recommendation letter workflow with eligibility enforcement, and an absence justification pipeline. Three interfaces — Next.js web for staff, React Native mobile for students, Spring Boot API underneath — with 179 endpoints serving five distinct user roles across an entire faculty.

• QR code + GPS attendance — dynamic codes expire in 5-10 minutes, Haversine radius validation eliminates proxy fraud
• Grade management — weighted CC/TP/Exam scoring, class statistics, GPA calculation, official PDF transcript generation
• Recommendation letter system — eligibility enforcement (grade ≥ 12/20, attendance ≥ 80%), full approval workflow, PDF with digital signature
• Five-role hierarchy: student, professor, coordinator, department head, director — each with a dedicated portal
• React Native mobile app — QR scanning, GPS check-in, push notifications, offline sync
• 179 REST endpoints across 24 entities, 80+ service classes, 22 Flyway schema migrations
• Real-time updates via WebSocket (STOMP) — live attendance dashboard for professors
• Disciplinary system with progressive sanctions that block recommendation eligibility
