Worked on the gotolanzhoubuycake/bare-repository, delivering an expanded character roster for the TRI faction in a game development context. Focused on data configuration using Paradox Script, the work involved defining new character entries, portraits, roles, traits, and abilities to broaden gameplay options and support future content updates. Emphasized a data-driven approach to roster modeling, enabling maintainability and minimal disruption to gameplay logic or UI. Managed asset preparation and roster data for quality assurance and release cycles, ensuring backward compatibility. Maintained strong Git hygiene for traceability and collaboration, with no major bugs reported or fixed during this development period.
