Worked on core improvements to Storybook and typescript-eslint repositories, focusing on enhancing type safety and dependency management. In Storybook, introduced type-safety enhancements to configuration files by leveraging TypeScript’s literal types and the as const assertion, which improved code predictability and reduced runtime errors in addon interactions and CSF strict mode. Addressed dependency stability in typescript-eslint by resolving missing ESLint peer dependencies in yarn.lock, preventing potential runtime issues and ensuring smoother builds. Demonstrated skills in TypeScript, YAML, and package management, contributing to more reliable configuration practices and improved developer onboarding across both projects through targeted code refactoring and configuration management.
