Emil Hüseynov | Backend Developer - .NET & Clean Architecture

About Me

Building Robust Backend Systems

I'm a backend-focused developer with deep expertise in the .NET ecosystem. My work revolves around creating scalable APIs, implementing clean architectures, and building systems that solve real business problems efficiently.

I specialize in ASP.NET Core, Entity Framework Core, and RESTful API design. From authentication systems to e-commerce backends and content management APIs — security, validation, and performance are always my priorities.

Beyond backend, I also have hands-on experience with Next.js and React, giving me a full-stack perspective on how frontend applications consume APIs and what they need from backend services.
