Worked on enhancing data access robustness in the 51Degrees pipeline-dotnet repository by introducing TryGet methods to the IFlowData and IData interfaces. This approach enabled safer, non-throwing data lookups and improved performance by combining property checks and retrieval using TryGetValue. Updated and expanded unit tests to verify correct fallback behavior when properties are missing, ensuring reliability. Enhanced observability by implementing explicit warning logs for unavailable properties. Maintained compatibility with MSTest v4 throughout the changes. The work focused on C# back end development, emphasizing performance optimization and thorough unit testing to deliver a more resilient and maintainable data access layer.
