Most clients reach out to me after struggling with slow .NET development, messy codebases, and APIs that break under scale. That usually happens when projects are built without the right architecture from day one. If you’re looking for a .NET Developer who builds fast, scalable, and production-ready systems, while using modern AI-assisted development to move quicker without sacrificing quality, you are in the right place. With 8+ years of experience as a .NET Full-Stack Developer, I combine deep expertise in C#, .NET Core, ASP.NET Core, ASP.NET MVC, and Web API with AI tools like Cursor, Claude, and GitHub Copilot to deliver high-quality .NET solutions faster than traditional development approaches. WHAT I DO AS A .NET DEVELOPER I specialize in building complete, end-to-end .NET applications — from backend architecture to frontend delivery and cloud deployment. My work includes: • ASP.NET Core API development — REST APIs, scalable Web APIs, and modern backend systems using .NET 6 and .NET 8 • C# backend development — Clean Architecture, CQRS, Domain-Driven Design (DDD), and SOLID principles • Full-stack .NET development — ASP.NET Core backend with React.js or Angular frontend • .NET Microservices architecture — distributed systems using ASP.NET Core, Docker, Kubernetes, and Azure Service Bus • Entity Framework Core — optimized database design with SQL Server, PostgreSQL, and Azure SQL • Third-party API integrations — Stripe, PayPal, Twilio, Plaid, and external services • Background jobs & event-driven systems — queues, schedulers, and scalable processing in .NET AI-ASSISTED .NET DEVELOPMENT I use AI as a real productivity tool — not just a buzzword. With Cursor, Claude, and Copilot integrated into my workflow: • ASP.NET Core APIs are developed faster with less boilerplate • C# code quality improves through AI-assisted reviews • Debugging complex .NET applications becomes quicker and more efficient • More focus goes into architecture, scalability, and system design This means you’re not just hiring one developer — you are getting the output of an optimized, high-efficiency development process. ASP.NET CORE & API DEVELOPMENT ASP.NET Core is at the core of everything I build. Every API I develop is: • Secure — JWT authentication, OAuth2, Azure AD integration • Scalable — built for cloud environments like Azure • Clean — structured using best practices like Clean Architecture • Documented — Swagger/OpenAPI included by default • Tested — unit and integration testing with xUnit / NUnit • Maintainable — versioned and ready for long-term scaling Whether it’s a new API, scaling an existing system, or modernizing legacy .NET applications — I focus on clean, reliable delivery. FULL-STACK .NET DEVELOPMENT I build complete systems where backend and frontend work seamlessly together: • ASP.NET Core + React.js (TypeScript-based modern apps) • ASP.NET Core + Angular (enterprise-grade applications) • Real-time applications using SignalR • Full database integration with SQL Server / PostgreSQL CLOUD & MICROSERVICES (.NET + AZURE) I design and deploy scalable cloud-native applications using Microsoft Azure: • Azure App Services, Azure Functions, Azure SQL • Azure Service Bus for event-driven architecture • Microservices using ASP.NET Core and Docker • Kubernetes (AKS) for container orchestration • CI/CD pipelines using Azure DevOps MY APPROACH Every project follows a structured approach: • Understand business requirements before coding • Design scalable architecture upfront • Use AI-assisted development to speed up delivery • Write clean, testable, production-ready .NET code • Stay available for improvements, scaling, and long-term support KEY PROJECT EXPERIENCE • Built HIPAA-compliant healthcare platform using .NET Core, ASP.NET Core Web API, and React.js, improving performance and data security • Developed microservices-based systems using ASP.NET Core and Azure, improving scalability and system reliability • Integrated third-party APIs (Stripe, PayPal, Twilio, Plaid) using .NET Web API, automating workflows • Migrated legacy applications to modern .NET Core / ASP.NET Core architecture on Azure, reducing infrastructure cost • Built enterprise platforms (CRM, LMS, SaaS, POS) using C#, ASP.NET MVC, .NET Core, and Entity Framework SERVICES I OFFER • ASP.NET Core web application development • .NET Web API & backend development • C# backend system design • Azure cloud architecture & deployment • Microservices development using .NET • Full-stack development (React.js / Angular + .NET) • API integrations & third-party services
