لم يكتب نبذة شخصيةI’m Mostafa Mohamed Khalil, a passionate .NET Back-End Developer with solid experience in C#, ASP.NET Core, Entity Framework, SQL Server, and RESTful API development. I specialize in building robust, scalable web applications and integrating APIs with modern front-end frameworks like React and Angular. With a background in Computer Engineering and Control, I combine strong technical problem-solving skills with clean, maintainable code practices. I’ve developed multiple full-stack projects, including e-commerce platforms, university management systems, and mobile app back-ends using .NET and Flutter. I also bring a broad tech foundation — Python, C++, Git/GitHub, AWS, and Linux — along with a solid understanding of data structures, algorithms, databases, and cloud computing. My approach focuses on writing efficient, secure, and well-documented solutions tailored to each client’s needs. If you’re looking for a reliable developer who values communication, quality, and deadlines, I’m here to help turn your ideas into production-ready applications.
