Worked on the foodplanner and foodplanner-api repositories, delivering four new features and a bug fix focused on stability and maintainability. Enhanced code quality through consistent refactoring, improved naming conventions, and better file organization using Dart and Flutter. Addressed runtime errors by implementing mounted context checks for safer UI navigation, and strengthened role-based routing with case-insensitive parsing and expanded logging. Improved API reliability by resolving JSON encoding issues and updating related tests. Refactored the Foodplanner API to register services via interfaces, increasing abstraction and flexibility. The work emphasized backend and frontend integration, robust error handling, and maintainable architecture using C# and ASP.NET Core.
