🎓 UniPair

Sprint 3 Evaluation · The Expats

📖 About the Project

UniPair is an application designed to match students across Europe with exchange universities based on personalized preferences. It uses an intelligent matching algorithm that considers country, language, climate, budget, academic program, and other personal preferences. Universities can share and manage their Erasmus-related information on the platform, continuously expanding the dataset of destinations.

🔍 Sprint 3 Observations

Build: ✅ Clean build passes. Uses jBCrypt for password hashing.
Run: ✅ Launches as "UniPair" (1200×828). Student registration, login, preference profile, and destination matching all functional.
Features visible: Student registration with hashed passwords, preference profile (country, language, climate, budget, academic program), intelligent matching algorithm with scored results, admin content management, and university data management.
Database: H2 embedded with Hibernate 6.1.2 ORM. Repository pattern across 7 entity types.
Test suite: ✅ 308 tests across 23 files, all passing — by far the most comprehensive test suite. Covers: domain (4 files), service layer (6 files), data access/repository (7 files), matching algorithm (5 files), and test fixtures. 23 test files
i18n: ✅ Full internationalization with 3 languages: English, Spanish, Basque (messages_en.properties, messages_es.properties, messages_eu.properties).
CI/CD: ✅ 4 GitHub Actions workflows: build-mac-client.yml, build-windows-client.yml, build-linux-client.yml, and build-check.yml. Full cross-platform CI coverage.
Design Patterns: ✅ Most mature architecture — Repository pattern (7 repository classes implementing DatabaseRepository<T>), Strategy pattern (ChecklistMatchingStrategy implements MatchingStrategy), and Builder pattern in test fixtures (PreferenceProfileBuilder, DestinationBuilder).

💬 Peer Feedback

Perfect consensus: Peer ratings were unanimous — every team member rated all their teammates 10 out of 10, with a self-rating of 9/10 showing humility. This reflects exceptionally balanced contribution and strong mutual respect across the entire team.

📊 Final Scores

Member	Score	Rationale
Tjark Berding	10/10	15.3h actual — led the team. Architected the mature multi-layer design (Repository + Strategy + Builder patterns), 4 CI/CD workflows, and the matching engine. Perfect 10/10 peer rating.
Kata Krisztina Koti	8/10	8.3h actual. Owned admin user and content management features, plus test creation. Perfect 10/10 peer rating.
Lili Anna Varga	8/10	7.3h actual. Implemented student registration, password hashing (jBCrypt), login authentication flow, and preference UI. Perfect 10/10 peer rating.
Ivan Katuša	8/10	4.3h actual — lowest on team but still rated 10/10 by peers. Self-rated 9/10 showing honest self-assessment. Contributed meaningfully despite fewer hours.

Team baseline: 🏆 308 tests (most in class, all passing). Most mature architecture: 7 Repository classes, Strategy pattern matching, Builder in test fixtures. 4 CI workflows. 3-language i18n. Perfect peer consensus (all 10/10). Best overall project.
