Javenture - Android Household Inventory Application

A team software engineering project that delivered a Java Android household inventory application with per-user cloud data and tested item-management workflows.

Problem / goal

The application needed to keep each user's inventory isolated while supporting reliable item entry, photos, tags, filtering, and persistent cloud-backed state.

My role

Android Developer on a team software engineering project.

What I personally contributed

• Implemented per-user inventory data flows using Firebase Authentication, Cloud Firestore, repository classes, and ViewModel-managed UI state.
• Built CameraX capture and gallery-selection workflows with Firebase Storage upload and deletion.
• Implemented batch tag assignment for selected items and contributed unit and instrumentation tests for core inventory flows.

Technical approach

• Separated Android UI state, repository logic, and Firebase operations to keep data access and screen behavior maintainable.
• Connected authenticated user identities to Firestore inventory records and Firebase Storage image objects.
• Covered core inventory behaviors with unit and Android instrumentation tests.

Key features

• Per-user authenticated inventory storage.
• CameraX capture and gallery-based photo selection.
• Firebase Storage image upload and deletion.
• Batch tag assignment for selected inventory items.
• Unit and instrumentation tests for core workflows.

Impact / results

• Delivered working team-owned Android features spanning UI state, cloud persistence, image handling, and batch item operations.
• Improved maintainability by separating Firebase access through repository classes and ViewModel-managed state.

What I learned

• Android applications are easier to test when UI state and cloud data access have clear ownership boundaries.
• Camera and storage workflows need lifecycle-aware error handling and tests around user-visible state changes.
