Worked on improving the liam-hq/liam repository by addressing inconsistencies in the command-line interface for ERD generation workflows. Focused on standardizing the PostgreSQL format flag to 'postgres' across both initialization and build commands, ensuring internal mappings and user-facing documentation reflected this unified approach. Utilized JavaScript and TypeScript to refactor CLI logic and update related documentation, reducing confusion and minimizing ERD-generation errors tied to format specification. The work involved a targeted bug fix that streamlined the user experience and decreased potential support issues. Demonstrated skills in CLI development, code refactoring, and documentation within a collaborative open-source environment.
