Quiero desarrollar una aplicación móvil en .NET MAUI que funcione tanto en iOS como en Android y que se sincronice con el punto de venta ya existente (escrito en C#). Funcionalidades clave • Menú digital con fotografías llamativas y una paleta de colores vivos que represente la identidad de la cafetería. • Carrito de compras, check-out con pasarela de tarjeta integrada y opción “Pago en efectivo al recoger”. • Programa de lealtad configurable: debo poder definir si los puntos se otorgan por monto gastado, número de pedidos o productos concretos, e incluso combinar reglas en el futuro. • Envío de “regalos” (créditos o productos) entre usuarios registrados. • Sistema de reseñas y calificaciones dentro de la app. Integración con mi POS Necesito recomendaciones técnicas para enlazar la app con el POS actual; estoy abierto a API REST directa, un middleware o incluso compartir servidor, siempre que la sincronización de inventario y órdenes en tiempo real sea estable y segura. Entregables mínimos 1. Código fuente MAUI bien documentado. 2. Propuesta de arquitectura de integración y pruebas de que la orden viaja hasta el POS. 3. Instaladores / builds listos para TestFlight y Google Play Console. 4. Guía rápida de configuración del programa de puntos y de los métodos de pago. Si algo no está claro indícamelo: prefiero cerrar los detalles antes de avanzar a la fase de desarrollo.

Hello, I will build your CAFEMORIA app in .NET MAUI with digital menu, cart, card gateway and cash on pickup, a configurable loyalty engine, and user-to-user gifting, all synced with your existing C# POS in real time. For POS integration, I will set up a REST API middleware layer so your POS stays untouched while orders and inventory sync both ways, with retry logic for any temporary connection drops. Questions: 1) Does your POS already expose any API endpoints, or will integration need direct database access? 2) Which payment gateway do you prefer (Stripe, Square, or another)? 3) Should combined loyalty rules be ready at launch, or single-rule first? Looking forward to discussing further. Best regards, Kamran

Hola amigo, soy experto en .NET C#, conozco xamarin desde sus inicios cuando era de paga (2014/2015), puedo desarrollar tu aplicación completamente como la requieres, además de que soy experto haciendo UIs a la medida si existe el Wireframe. En caso de que no tengas UI, puedo proponer según tus requerimientos, me gustaría darte apoyarte en tu proyecto, si gustas puedo darte una demo de alguna vista que tengas planeada sin costo. Para lo de la integración de tu POS actual, podría ser una API REST, el único tema que veo es el manejo de stock, hay cosas que se tendrían que modificar en tu POS actual para cumplir con la sincronización exacta. Como por ejemplo, bloquear cantidades si estan pensadas en usarse en la app o en el pos. Creo que el punto mas importante de tu desarrollo es establecer el MVP y la UI testeable (wireframe) del proyecto para saber que lo que se va a desarrollar cumple y es lo que se requiere. Espero tu mensaje, saludos!

I’ve built .NET MAUI mobile apps integrated with existing C# POS systems, ensuring stable real-time synchronization without disrupting live operations. Proposed architecture: Mobile app built in .NET MAUI using clean MVVM structure with clear separation between UI, business logic, and service layers. Recommended integration via an ASP.NET Core REST API middleware that acts as a secure bridge between the app and your POS. This prevents direct exposure of the POS and allows validation, logging, rate control, and scalability. POS Integration Strategy: Expose controlled endpoints from the POS or connect via a secure service layer. Use SignalR or WebSockets for real-time sync of inventory and order status. All order submissions are transactional to prevent stock inconsistencies. Core Features: Dynamic digital menu with optimized image caching and brand-aligned UI. Shopping cart and checkout with Stripe (or compatible gateway) plus “Cash on Pickup.” Configurable loyalty engine with rule-based logic (amount spent, order count, product-based rewards, expandable for combined rules). Peer-to-peer gift system (credits or products) with secure balance validation. In-app reviews and ratings module. Deliverables: Fully documented MAUI source code. Integration architecture proposal with verified POS order sync. TestFlight and Google Play ready builds. Quick setup guide for loyalty rules and payment configuration. Timeline: 6 - 8 weeks

Hi CAFEMORIA. I have 7+ years building cross-platform mobile apps with .NET MAUI and integrating C# backends and POS systems. I will implement a MAUI app with a vibrant, photo-rich menu, cart, card gateway + cash-on-pickup, configurable loyalty rules, gifting and reviews, and deliver well-documented source code and TestFlight/Play builds. For POS integration I propose a secure RESTful API with optional lightweight middleware and WebSocket events for real-time inventory and order sync, plus integration tests proving orders reach the POS. Why We Work Together: - Proven MAUI + POS integrations - Delivery of code, architecture docs and test builds - Focus on secure real-time synchronization Best Regards, Sherman
