Worked on the beyond-all-reason/Beyond-All-Reason and beyond-all-reason/spring repositories, focusing on targeted bug fixes that improved reliability and gameplay accuracy. Addressed a projectile range issue by ensuring overrange_distance was correctly multiplied by rangeMult, aligning mod options and reducing gameplay discrepancies using Lua scripting and game development skills. In the spring repository, restored lowercasing of file extensions within the FileSystem module, enhancing cross-platform consistency and simplifying the code path in C++. Added unit tests to validate these changes, strengthening test coverage and CI reliability. Demonstrated careful code isolation, clear commit practices, and a disciplined approach to regression prevention and software testing.
