Nov 1, 2025

November 2025 — mage project performance highlights: consolidated card data model, hardening verification for double-faced/transforming cards, and gameplay abilities enhancements. Key deliverables: Card Data Model Refactoring and Consolidation unified A–I transforming cards into a single class/file, reducing duplication and easing maintenance; CardScanner and Verification Enhancements strengthened double-faced/transforming card validation, introduced per-name/set checks, updated tests to cover both sides, and adjusted behavior; Gameplay Abilities Enhancements added/refined abilities across multiple cards to improve mechanics and player experience. Major bugs fixed and stability improvements: prevented abilities on the main card for double-faced cards, fixed verification gaps, and stabilized CardScanner by reverting a prior change. Overall impact: higher maintainability, more robust rule enforcement, and better test coverage, enabling faster, safer feature delivery. Technologies/skills demonstrated: Java/OOP refactoring, test-driven development, unit/integration testing, rule verification, and maintainable code architecture.
