Worked on stabilizing the CLI handler import and export process for the Lightning-AI/litData repository, focusing on backend development with Python. Addressed a critical ImportError by adding a missing __init__.py file and correcting module imports and exports, which restored broken functionality and improved CLI reliability. Updated packaging exports and ensured compliance with the Apache 2.0 license by aligning licensing headers. Incorporated pre-commit hook fixes to enhance code quality and maintain consistency across the codebase. These efforts contributed to smoother data workflows and improved maintainability, demonstrating a methodical approach to resolving bugs and refining backend infrastructure using Python.
