Tech Lead - Java/AWS

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 

• WPF, XAML, MVVM, C# (.NET 6/8),
• 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. 

Qualification 

• B.E. / B.Tech / MCA in Computer Science
• 2–4 years WPF desktop development experience
