Worked on foundational code quality improvements within the pagopa/interop-be-monorepo, focusing on enhancing maintainability and consistency across the TypeScript front end. The primary effort involved a comprehensive linting pass, unifying type annotations, and removing unnecessary comments to streamline the codebase. Adjustments to existing tests ensured alignment with updated coding standards, supporting future development and safer refactoring. By establishing consistent tooling and enforcing standardized practices, the work reduced potential errors and set the groundwork for increased team velocity. The approach emphasized code health and readability, leveraging TypeScript and front end development skills alongside robust testing methodologies to improve overall project stability.
