Worked on the typescript-eslint/typescript-eslint repository, focusing on resolving a critical correctness bug in the ESLint plugin related to generic classes. Addressed an issue where ignored base types within generic classes were not properly recognized, which previously led to inaccurate type checking and lint results for TypeScript users. The solution involved targeted static analysis improvements using TypeScript and ESLint, ensuring that the plugin now correctly honors ignored base types. Collaborated closely with reviewers to refine the implementation, resulting in more reliable linting for complex generics. This work reduced false positives and improved the overall developer experience for teams relying on strict linting.
