A .NET Core Developer specializes in building modern, scalable, and high-performance applications using .NET Core, an open-source, cross-platform framework developed by Microsoft. This role involves developing server-side logic, creating APIs, and working with databases to build robust, web-based applications that run on various platforms, including Windows, Linux, and macOS. .NET Core Developers are skilled in C# programming, utilizing the framework’s features like dependency injection, middleware, and asynchronous programming to create efficient, maintainable code. They work with front-end teams to integrate user interfaces with back-end systems, ensuring seamless communication between the client and server. In addition, .NET Core Developers are responsible for writing unit tests, debugging, and optimizing the performance of applications. They also ensure that the applications are secure and scalable, implementing best practices for data storage, security, and cloud integration (often leveraging services like Azure). Strong knowledge of modern development tools like Visual Studio, version control (Git), and containerization technologies (e.g., Docker) is essential for success in this role. .NET Core Developers typically work in Agile environments, collaborating with cross-functional teams to deliver high-quality software.
