Hire the Best .NET Developers

Throughout my career, I've worked on complex software projects where reliability, performance, maintainability, and clean architecture are critical. I specialize in designing robust backend systems with C# and .NET, while also working across frontend, databases, cloud infrastructure, and DevOps when the project requires full-stack ownership. What I deliver: - Build scalable REST APIs using C#, ASP.NET Core, and .NET 6/7/8 - Design enterprise applications using Clean Architecture, SOLID, CQRS, MediatR, and Repository patterns - Develop microservices and distributed backend systems - Build modern web applications using React.js, Angular, Blazor, TypeScript, and JavaScript - Design and optimize PostgreSQL, SQL Server, and Oracle databases - Improve application performance through query optimization, Redis caching, asynchronous processing, and efficient API design - Build background services, scheduled jobs, and workflow automation - Integrate third-party APIs, enterprise systems, payment platforms, and SaaS services - Containerize applications with Docker and support cloud deployments - Build CI/CD pipelines using GitHub Actions and modern DevOps practices - Write reliable automated tests using xUnit, NUnit, Moq, and integration testing frameworks - Debug production issues, perform root-cause analysis, and improve system stability Core technologies: C#, .NET, ASP.NET Core, Web API, Entity Framework Core, LINQ, SQL Server, PostgreSQL, Oracle, Redis, Docker, Azure, AWS, Microservices, REST APIs, CQRS, MediatR, Clean Architecture, React.js, Angular, Blazor, TypeScript, JavaScript, GitHub Actions, CI/CD, xUnit, NUnit, Playwright My approach is simple: understand the business problem first, design the right technical solution, and deliver clean, maintainable software that can continue to evolve as the business grows. Whether you need a senior .NET engineer to build a new application, modernize an existing system, integrate multiple services, optimize a slow backend, or resolve challenging production issues, I can take ownership from architecture through implementation and delivery.

I build scalable, production-ready .NET and Azure platforms - microservices, SaaS dashboards, enterprise APIs, and React/Angular frontends - delivered on time and built to last. 10+ years as a .NET Architect and Full Stack Developer, leading end-to-end architecture and delivery for Fortune 500 companies and funded startups across healthcare, finance, logistics, and e-commerce. I combine deep ASP.NET Core backend expertise with Azure cloud-native deployment and modern React/Angular frontends, so you get one engineer who owns the complete system - not a handoff between five specialists.

🏆 Top Rated Plus · ✅ 50+ jobs completed · ⏳ 15+ years shipping full stack products Most "full stack" developers own the frontend and hand off the backend to someone else. I own both - React/Next.js on the frontend, .NET Core or Node.js on the backend, deployed and production-ready end to end. That means fewer handoffs, faster iteration, and a system that's architected consistently from database to UI instead of stitched together. ──────────────────────────────── ROLES I TAKE ON (15+ YEARS EXPERIENCE) ──────────────────────────────── ✔ Full Stack Developer / Full Stack Engineer ✔ React Developer / React.js Developer / Next.js Developer ✔ Frontend Developer - component architecture, state management, performance ✔ .NET Developer / .NET Core Developer / C# Developer (backend & full stack) ✔ SaaS Developer / Multi-Tenant SaaS Architect ✔ Angular Developer (8–20) for teams standardized on Angular ──────────────────────────────── 🛠️ CORE TECH STACK ──────────────────────────────── Frontend: React.js, Next.js, Angular, TypeScript, JavaScript, Tailwind CSS Backend: .NET Core, ASP.NET Core, C#, Node.js, Web API, Entity Framework, Microservices, REST APIs Cloud & DevOps: Microsoft Azure, AWS, Docker, CI/CD Database: SQL Server, PostgreSQL, MongoDB Also comfortable with: Python (FastAPI, Django, Flask) used when a project calls for it ──────────────────────────────── 🚀 PROJECTS I'VE DELIVERED ──────────────────────────────── 🔹 NinjaDAM - Multi-tenant SaaS, AWS S3/CloudFront, subscription billing.
