Project details

You will get a production-ready REST API built with .NET stack and C#, fully documented, tested, and deployed to Azure. With 8+ years of .NET development experience and a 100% Job Success Score, I deliver clean, maintainable backend solutions on time — not just working code, but code you can actually build on.
Every API I deliver includes JWT authentication, SQL database integration via Entity Framework Core, Swagger documentation, unit tests, and Azure deployment. I follow Clean Architecture principles so your codebase stays organized as it grows.
Whether you need a simple CRUD API, a complex multi-role system, or integration with third-party services — I'll scope it clearly, communicate throughout, and hand over full source code with documentation. No surprises, no disappearing after delivery.
