Natalie Hergesheimner contributed to the cisagov/cset repository by developing the Assessment Mode feature, which introduced a new boolean column, assessormode, to the ASSESSMENTS table. This backend enhancement, implemented in C# with supporting SQL schema changes, enables the application to support differentiated assessment workflows based on user roles or assessment types. By focusing on data modeling for feature flags, Natalie ensured the system is positioned for future governance and workflow variations without requiring disruptive refactoring. The work demonstrated clear commit traceability and aligned with the project roadmap, reflecting a thoughtful approach to backend development and database schema design.
