Sr Java Technical Lead

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. 

Required Skills 

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 

Good to Have 

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 

AI-Assisted Development (Mandatory Mindset) 

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.
