PROJECTS
PixelDoku – pixel-art Sudoku game for Android
GitHub | Itch.io
Unity, C#, Google Mobile Ads, JSON, PlayerPrefs

• Partially refactored legacy code by extracting critical components from large classes, reducing tight
coupling, and moving key systems toward MVC and an event-driven approach.
• Developed a puzzle generator based on core templates and a matrix of symmetric permutations.
• Built a backtracking solver to validate solution uniqueness and estimate level difficulty.
• Moved difficulty configuration into ScriptableObjects to support faster balance testing without code
changes.

ClawClimb-Risk-Reward – vertical platformer with meta-progression elements
GitHub | Itch.io
Unity, C#, VContainer, Firebase Analytics, Unity Analytics, JSON

• Introduced Dependency Injection with VContainer, reducing coupling between gameplay systems and
simplifying testing.
• Created a data-driven upgrade system using ScriptableObjects, rarity ranks, and combined effects.
• Implemented the core gameplay loop, enemy logic, pickups, and 6 platform variations.
• Developed meta-progression with JSON-based save logic and connected Firebase Analytics and Unity
Analytics for balance analysis.
