nitishpoudel/Expenses-tracker — reverse-engineered prompt

I want a simple expense tracker web app with a frontend and backend. Users should be able to add expenses with an amount, date, category, and note, see them in a clean list, edit or delete mistakes, and view a basic monthly total so they know where their money is going.

Keep the design simple and mobile friendly, with clear empty states and validation so bad amounts or missing dates don’t get saved. If there isn’t login already, just make it work for one local user for now and store the data through the backend.

Please set up the project so it runs easily from the existing Frontend and Backend folders, include any needed environment example, and make sure the main flows actually work end to end. Look up current docs online if you need to.
