👋 Looking for a senior .NET developer / C# developer / ASP.NET Developer backed by a Full Stack Microsoft Gold Partner team? I specialize in architecting and delivering high-performance ASP.NET, C#, and cloud-native solutions – from Windows desktop systems to modern web apps with React, Angular, Blazor, Xamarin, and .NET MAUI. With 25+ years in enterprise software engineering (and commercial work since 1998), I’ve led and shipped 500+ .NET and ASP.NET projects as a full stack developer and web developer – including mission-critical systems for finance, healthcare, logistics, manufacturing, and government. Our solutions consistently cut infrastructure costs by up to 40%, improve response times by 60–80%, and increase platform stability and uptime to 99.9%+. 🏆 Our .NET / C# / Full Stack Results ✔️ 25+ years of experience as a .NET developer, ASP.NET developer, C# developer, Windows Developer, Desktop Developer, and web developer ✔️ 500+ production .NET / ASP.NET / C# systems delivered for startups, SMEs, and enterprises ✔️ 40+ countries served with complex enterprise apps, SaaS platforms, and integration-heavy backends ✔️ Legacy .NET Framework and WebForms systems modernized into ASP.NET Core, Blazor, React, and Angular solutions ✔️ High-load .NET API and ASP.NET API backends handling millions of requests per day with sub-second latency ✔️ Cross-platform mobile and desktop solutions using Xamarin, .NET MAUI, React Native, and Flutter ✔️ Proven experience collaborating alongside Java developer, python developer, flutter developer, laravel and ruby on rails teams in polyglot environments 🚀 Enterprise .NET & C# Backend Development I design and build robust server-side architectures using .NET, ASP.NET, and C# for APIs, microservices, and enterprise line-of-business systems: - Clean architectures with ASP.NET Core, .NET API, ASP.NET API, REST, GraphQL - High-throughput middleware, background workers, and event-driven processing - Secure authentication and authorization (JWT, OAuth2, Azure AD, IdentityServer) - Integration with SQL Server, PostgreSQL, MySQL, MongoDB, Redis, message queues - Cloud-native patterns on Azure, AWS, and hybrid infrastructure - Performance tuning, caching, profiling, and scalability planning As a .NET developer and .NET full Stack developer, I frequently work in mixed teams where C#, React, Angular, python, flutter, laravel, and Node.js coexist – ensuring the .NET side is rock-solid and plays nicely with everything else. 🖥 Windows / Desktop Developer with C# and .NET I have deep experience as a Windows Developer and Desktop Developer building rich client applications: * WinForms and WPF business applications with MVVM and dependency injection * C# asp.net developer for windows application modernization and API integration * Offline-first enterprise tools, synchronization, reporting, and printing pipeline integration * Complex UI components with DevExpress, Telerik, custom controls, and hardware integration * Migration from legacy desktop stacks into modern .NET, ASP.NET, and cloud backends 🌐 Full Stack Developer – Web Apps with React, Angular & Blazor On the frontend, I build modern SPA and hybrid apps as a full stack developer and web developer: * React and Angular frontends integrated with ASP.NET Core and .NET API backends * Blazor Server and Blazor WebAssembly portals sharing C# code between client and server * Responsive dashboards, admin panels, and data-heavy reporting interfaces * Role-based access, multi-tenant UI, localization, and accessibility * Tight integration with REST, gRPC, SignalR real-time channels, and external APIs I routinely combine C#, React, Angular, and ASP.NET in a cohesive stack so that both backend and frontend are maintainable, testable, and future-proof. 📱 Cross-Platform & Mobile – Xamarin, .NET MAUI & Beyond As a Xamarin and .NET MAUI specialist, I build cross-platform applications that share C# logic across devices: - Xamarin.Forms and .NET MAUI apps for iOS, Android, macOS, and Windows - Shared business logic with platform-specific UI customization where needed - Integration with device sensors, push notifications, offline storage, and secure keychains - Working alongside other mobile stacks such as React Native and Flutter when projects require it This gives you the benefit of a single C# codebase with native-grade performance and consistent behavior across platforms. ⚙️ Broader Tech Ecosystem & Collaboration While .NET, ASP.NET, and C# are my core, I’m comfortable in polyglot environments that involve: - Collaboration with Java developer and python developer teams on backend or data pipelines - Integrating services built in flutter, laravel, ruby on rails, Node.js, or Go into a .NET ecosystem - Acting as the bridge between legacy Microsoft stacks and modern cloud or JavaScript-heavy stacks This holistic view helps us select the right tool for each part of the system while keeping .NET at the heart of your mission-critical.
