Worked on the kedro-org/kedro repository to enhance the reliability of CLI user prompts by addressing a bug in regex validation. Focused on preserving the original casing of user input, the solution removed unnecessary lowercase transformations and implemented a case-insensitive regex validator, ensuring validation accuracy without altering user data. Updated both Python code and YAML configuration files to align with this approach, and added targeted tests to prevent future regressions. Demonstrated skills in CLI development, configuration management, and regular expressions, with a test-driven workflow that prioritized correctness and user experience in data science project initialization and configuration processes.
