WPF Developer

Role Summary

• We have an existing Android-based POS application that needs to be migrated and rebuilt as a Windows desktop application using WPF.
• You will re-architect the Android app's features, UI flows, and business logic into a full-featured WPF application with SQLite local storage, EF Core, and existing REST API integration.
• Responsibilities Analyze the existing Android POS app and re-architect it as a WPF desktop application.
• Rebuild all screens and workflows (billing, cart, product catalog, orders, reports) in WPF / XAML following MVVM pattern.
• Implement local data storage using SQLite + Entity Framework Core (Code First, migrations).
• Integrate with the existing backend REST APIs (same APIs used by Android app) for product sync, orders, payments, and authentication.
• Ensure feature parity between Android and Windows versions.
• Integrate Windows-specific hardware barcode scanners, receipt printers, cash drawers.
• Apply Dependency Injection, async/await, and SOLID principles throughout.

• Use GitHub Copilot / Cursor / Claude to convert Android (Java/Kotlin) logic to C# WPF code efficiently.
• Use AI tools for boilerplate generation ViewModels, EF Core models, API service classes, XAML layouts.
• Leverage AI for code review, refactoring suggestions, and identifying platform-specific differences (Android vs Windows).
• Use AI-assisted documentation and inline commenting to maintain code clarity during migration.
• Comfortable evaluating, validating, and refining AI-generated code not just accepting output blindly.
