Aaron Downing focused on internal code cleanup and minor refactoring for the NHSDigital/communications-manager-api repository, targeting technical debt reduction and improved maintainability. Working primarily with C# and .NET, Aaron enhanced code readability and modularity without introducing user-facing changes. The approach emphasized adherence to coding standards and repository health, laying a stronger foundation for future feature development. By clarifying module boundaries and streamlining the codebase, Aaron enabled faster onboarding for new developers and safer, more efficient future releases. Although no major bugs were addressed during this period, the work provided essential groundwork for upcoming enhancements and long-term project stability.
