Worked on ProjectIgnis/CardScripts to expand and centralize card recognition within the game by defining new constants for specific cards, including ANCIENT FAIRY DRAGON and Temple of the Kings. Leveraged Lua scripting and Git version control to introduce dedicated constants in card_counter_constants.lua, replacing hard-coded values and enabling scalable, maintainable support for future cards. Focused on data-driven constant management to improve accuracy and consistency across game logic, while establishing clear traceability for changes. The approach enhanced maintainability and data integrity, supporting easier code reviews and future refactoring, with all work delivered as feature additions and no bug fixes during the period.
