Review Summary

Your implementation successfully meets all requirements for the expense tracking app. You've correctly implemented 2 collections (users and expenses) with 5 endpoints each, properly set up in-memory storage that resets on server restart via init functions, and implemented appropriate 400/404 error handling throughout. The code follows a clean MVC architecture with proper separation across routers, controllers, and services. The Express app is correctly exported from createServer() without calling listen(), allowing it to be used externally as intended. All checklist items from the task description have been satisfied.
