Worked on the sorbet/sorbet repository to enhance the package import system by introducing a feature that differentiates test helper imports from runnable test imports within package mode. This involved refactoring import logic to accurately identify and handle distinct import types, as well as strengthening package visibility checks to prevent misconfigurations. Improvements were also made to the autocorrect functionality, providing more precise suggestions for import statements and reducing false positives. The work leveraged C++ and Ruby, drawing on skills in code analysis, compiler development, and testing frameworks to improve code hygiene, streamline onboarding, and support maintainability across the codebase.
