Worked on the nightingaleproject/vital-records-dotnet repository to expand the BFDR.CLI tool’s data processing capabilities by adding support for fetal death records alongside existing birth record functionality. Refactored the command-line interface in C# to accept a record type argument, updating both command parsing logic and related documentation. Enhanced test coverage to ensure the new fetal death record flow was robust and regression-safe. Focused on CLI development and data conversion, leveraging FHIR and IJE standards for record processing. These changes improved maintainability and positioned the tool for broader data handling in future releases, addressing evolving requirements in vital records management.
