Worked on the Ruff Linter in the astral-sh/ruff repository, delivering a targeted bug fix that addressed type-parameter scope handling for Python typing scenarios. The solution involved refining the typing-context logic to improve the accuracy of private name import detection, reducing false positives and negatives in type analysis. A generic helper function was introduced to support the updated scope logic, and test snapshots were revised to reflect changes in code structure, ensuring robust regression coverage. This work leveraged both Python and Rust development skills, with a focus on linting and static analysis, and contributed to more reliable Python code quality checks.
