Worked on the cdisc-org/cdisc-rules-engine repository to deliver new features supporting clinical data standards and terminology integration. Built a unified external dictionaries framework, adding support for UNII and SNOMED dictionaries, and enhanced reporting to include dictionary provenance and versioning. Leveraged Python for backend development, API integration, and CLI tooling, focusing on maintainability and standards compliance. Improved the cache update mechanism to support API-key-optional flows and robust handling of empty data responses, updating tests and documentation accordingly. Emphasized code quality through refactoring, configuration management, and expanded unit testing, resulting in a more reliable and configurable validation pipeline for clinical workflows.
