We have an existing Android-based POS application that needs to be migrated and rebuilt as a Windowsdesktop application using WPF. You will re-architect the Android apps features, UI flows, and business logicinto 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.

• C# (.NET 6/8), WPF, XAML, MVVM
• Entity Framework Core + SQLite
• REST API consumption (HttpClient, JWT auth, JSON handling)
• Ability to read and understand Android (Java/Kotlin) code and translate logic to C#
• Git, Visual Studio
• 2-4 years WPF desktop development experience

• Prior Android-to-Windows or mobile-to-desktop migration experience
• Payment gateway integration (Razorpay / Stripe / Paytm)
• PDF / receipt generation (RDLC / FastReport)
• POS, billing, or retail domain experience

We expect the candidate to actively leverage AI tools to accelerate the migration and development process:

• 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.
