Hello there, I can build your Xamarin MAUI mobile app to mirror the core workflows of your existing C# Windows application, with seamless integration to both local and Azure MSSQL databases. The app will include responsive forms for login with OTP-based authentication, sales dashboards with date-range and category filters, restaurant KOT order forms that print directly to the kitchen, and sales invoice forms with printing support. Device management and persistent login handling will be implemented to align with your security and operational requirements, ensuring the app is both fast and production-ready across Android and iOS. Questions: – Do you already have APIs for interacting with your local and Azure MSSQL databases, or should I build them alongside the mobile app? – For printing (KOT and invoices), should the app connect via Bluetooth/WiFi printers directly, or through the existing Windows application’s print services? I am a TOP Rated Freelancer, and you can check my past work and reviews here as well: https://www.freelancer.com/u/kamran2012 Looking forward to potentially working together on this project.

Hi, I can build your Xamarin MAUI mobile app to mirror the key functionality of your existing C# Windows application, with seamless integration to both local and Azure MSSQL databases. A critical challenge here is ensuring fast, secure, and stateful login—I'll implement persistent sessions with OTP fallback and centralized device management.
