CW The key here is building the mobile app without creating a separate technology island from your existing .NET 8 system. I would first review the current ASP.NET Core architecture, authentication, APIs, database model, and Azure deployment so the mobile application can reuse the right services safely. For mobile, I’d recommend either .NET MAUI if you want to stay strongly aligned with the Microsoft ecosystem, or React Native if the UI and mobile development roadmap benefit from a separate cross-platform layer. The decision should be based on your existing codebase and long-term maintenance needs rather than preference alone. I would keep mobile-facing APIs versioned and clearly separated, handle authentication/token refresh securely, and make sure changes to existing backend functionality are regression-tested before deployment. On Azure, I can work around application deployment, configuration, logging, storage, databases, CI/CD, and environment separation as required by the existing setup. I’m comfortable working in an existing codebase, debugging issues methodically, and explaining implementation decisions rather than relying on generated code without understanding it. Which mobile framework are you currently leaning toward, and is the existing .NET 8 backend already exposing APIs for the features you want in the app?

Hi there, let's have short meeting if you wanna discuss the app and long-term plan. I can work across .NET 8, ASP.NET Core, Azure, Android and iOS, so you won’t need separate devs for backend, mobile and cloud. I can first review your existing .NET 8/Azure codebase, APIs, DB and auth flow, then build the mobile app around the existing system without breaking current features. I’m comfortable with API integration, authentication, database work, Azure services, debugging, deployment and adding new features on both web and mobile. I also use AI tools when useful, but I understand and debug the code myself. I’m interested in a long-term role and can take ownership of tasks from development to deployment.

You need a developer who can extend an existing .NET 8 and Azure platform into a reliable Android/iOS app while also maintaining the backend, APIs, and cloud infrastructure behind it. I have 9+ years of full-stack experience working across mobile, backend, and cloud systems. At Poundit, I worked on production e-commerce systems with Django/Node backends and mobile-focused workflows, while also handling APIs, databases, integrations, and ongoing feature development. For this project, I can work with your existing ASP.NET Core codebase, build the mobile application, connect it with your APIs, and handle Azure services, authentication, deployment, debugging, and future improvements. I focus on understanding the code I write and maintaining clean, explainable implementations rather than just generating code.

Hi - Abror here ".NET 8 + AZURE + ANDROID/iOS" — you need one developer who can work across your existing backend, mobile apps, and Azure without breaking what already works. I’d start by mapping the existing ASP.NET Core APIs, authentication, database, and Azure services before building the mobile layer. For the app, I’d use .NET MAUI where the existing requirements fit, keeping shared business logic between Android and iOS while leaving platform-specific features separate when needed. The key edge case is API compatibility: mobile changes must not break the current website. I’d therefore keep API changes backward-compatible and test the existing web flows alongside each mobile feature. Which mobile features from the current website do you want included in the first release? Looking forward to working with you.

CW Hi, how are you planning to handle cross-platform state synchronization between your existing .NET 8 backend and the new mobile clients to ensure data consistency during offline-first operations? To scale your ecosystem, I will implement a robust API-first architecture using .NET 8, leveraging Azure App Service and SQL Database to ensure the mobile app communicates seamlessly with your existing infrastructure. We will utilize MAUI or React Native for the cross-platform mobile layer, ensuring a native feel while maintaining a shared business logic library. I recommend implementing Azure Redis Cache for your API responses; this significantly reduces database load and slashes latency for mobile users on unstable cellular networks. I am available for a quick call to discuss the project further and can also share similar projects I have worked on in the chat. Thanks
