I have a pair of .NET MAUI apps already compiled and running on our local devices; the only missing piece is a rock-solid connection layer to our on-premise SQL Server sitting on the same LAN. The apps must be able to read, write, and update data in real time without touching the public internet. What I need from you, in the next 24 hours, is a lean, well-commented integration that: • Detects the SQL Server over the local network and establishes a secure connection. • Exposes asynchronous CRUD methods our existing ViewModels can call directly. • Keeps records in sync instantly (no polling) while both app and server stay inside the LAN. • Handles dropped connections gracefully and retries without data loss. Feel free to use Entity Framework Core, SignalR, or straight [login to view URL]—whatever lets you deliver clean, reliable code fast. I’ll provide the table schema, sample data, and a test machine on the network the moment we start. When you’re done, hand over the source files plus a brief setup note so my team can plug the layer straight into our repository and hit Build. If you can jump on a quick screenshare to walk through the hand-off tomorrow, even better.

I’ve reviewed your requirement and this is my understanding: you have two existing .NET MAUI apps running locally, and you need a secure, LAN-only real-time connection to your on-premise SQL Server. The integration must support asynchronous CRUD operations, instant data sync, and robust error handling, all without touching the public internet. I have 8+ years of experience building enterprise .NET applications with Entity Framework Core, SignalR, and real-time LAN connectivity. I specialize in lean, well-documented, production-ready integration layers that your existing ViewModels can consume directly. I’m ready to start immediately and can provide a robust, real-time, LAN-only connection layer that your MAUI apps can use seamlessly. Best Regards, Deepak

Olá, Li atentamente o escopo do PONGPONTO ID e compreendi que você precisa de um sistema completo de autenticação e área de membros integrado ao Webflow com Firebase, incluindo integração com Shopify e redirecionamento via NFC mantendo a sessão ativa. Sou desenvolvedora focada em desenvolvimento web e integrações, com experiência em JavaScript, estruturação de sistemas de login e organização de fluxos de usuários. Tenho trabalhado com projetos que envolvem lógica de autenticação, controle de dados e integração entre plataformas. Minha abordagem para o seu projeto será: • Configurar Firebase Authentication (email e senha) com controle seguro de sessão • Estruturar Firestore para armazenar perfil, níveis e pontuação • Proteger páginas privadas no Webflow utilizando verificação de autenticação antes do carregamento • Criar dashboard dinâmico mobile first • Integrar Shopify via API ou Webhooks para atualizar status e pontos automaticamente • Configurar a lógica de redirecionamento via NFC garantindo persistência da sessão • Documentar toda a estrutura para facilitar expansão futura Trabalho no modelo de €10 por hora, com organização por etapas e acompanhamento de progresso. Antes de iniciar, gostaria de confirmar dois pontos: A integração com Shopify será baseada em Webhooks ou API direta? O NFC apenas redireciona para URL ou precisa validar algo adicional no backend? Posso iniciar imediatamente após alinharmos esses detalhes. Fico à disposição.

Hi there, I understand you're looking to establish a robust connection between your .NET MAUI apps and your on-premise SQL Server, ensuring real-time data synchronization without involving the public internet. This is crucial for maintaining data integrity and providing a seamless user experience. To achieve this, I propose a tailored integration that will securely detect your SQL Server on the local network and implement asynchronous CRUD operations via a reliable connection layer. Leveraging tools like Entity Framework Core or SignalR, I can ensure that records are synced instantly while maintaining stability during any dropped connections. My focus is on delivering clean, well-structured code that your existing ViewModels can call effortlessly. With the table schema and sample data you provide, I can hit the ground running and guarantee a smooth handoff with comprehensive documentation. Would you be available for a quick screenshare tomorrow to discuss your specific requirements further? https://www.freelancer.com/u/proggon Best regards, Wahaj Barlas.

Hi! I can help you ship a LAN-only, rock-solid data layer for your .NET MAUI apps quickly and cleanly. Approach (reliable + fast): Local discovery: detect SQL Server on the LAN (UDP broadcast / SQL Browser) and validate connectivity, then build the final connection string. Secure connection: TLS-enabled SQL connection, least-privilege SQL user, optional Windows auth if your environment supports it. Async CRUD API: a small service layer (IDataService + repositories) your existing ViewModels can call directly. Instant sync (no polling): SignalR self-hosted on your on-prem server to push change events to devices in real time (LAN only). Clients update local UI immediately. Resilience: automatic reconnect + queued writes for offline moments, retry with backoff, and “at-least-once” delivery without losing data. Deliverables: Source files: connection/discovery, CRUD services, SignalR client + server hub, retry/offline queue. Brief setup note + sample config (connection string, ports, firewall rules). Optional screenshare walkthrough for the handoff.

This requirement goes beyond a simple direct SQL connection. For a secure, production-safe LAN architecture with real-time synchronization (no polling), the correct approach is: MAUI App → ASP.NET Core API (inside LAN) → SQL Server with SignalR handling instant updates. This prevents exposing SQL credentials in the client app and provides proper connection management, logging, and retry handling. I will deliver: • Lightweight ASP.NET Core API inside your LAN • Async CRUD service layer for ViewModels • Secure SQL Server integration • SignalR-based real-time updates (no polling) • Automatic reconnect & retry logic • Clean, well-commented source files • Setup notes + walkthrough session Delivery: 2 days Total Budget: $350 (split into 2 milestones) I focus on clean, production-grade implementations that remain stable long-term.
