Unity-Based Daily Expense Tracker App for Android

**Project Description: Expense Tracker Android App in Unity**

I need a Unity developer to create a daily expense tracker app with a well-organized structure for recording expenses. The app should categorize expenses into folders as follows:

- **Yearly Folder**: Each year should have its own folder (e.g., "2025").
- **Monthly Folder**: Inside each year, folders for each month (e.g., "January").
- **Daily Lists**: Within each month, daily lists (e.g., "1st Jan") for tracking daily expenses.

For each daily list:
- Allow creating subsections (e.g., Food, Bills) that are user-renamable.
- Each subsection should include a title (e.g., "Pizza") and an amount.
- Automatically calculate totals for each subsection and the entire daily list.

The app must also:
1. Display grand totals for each day, month, and year in a dynamic UI.
2. Save and load expense data as JSON files, ensuring data persistence.
3. Provide an intuitive UI for adding, deleting, renaming, and viewing expenses.

Look at this Sample UI for reference:

Deliverables:
1. Unity project files
2. Working app build.
3. Well documented, modular code, dynamic UI and best practices.
Please include project completion timelines, and if possible, samples of similar past work.
