Android Office Manager App Development

I need an experienced Android developer to build an Office Manager app for personal use. The app should include Login & App Lock, To-Do Manager, Location-wise Accounts Ledger, Vendor Management, Purchase Management, Notesheet Tracking, Reminders, Reports, Backup & Restore, and a modern Material Design UI. The app should be developed in Kotlin with Jetpack Compose and Room Database. The source code and full ownership must be transferred to me after project completion.
