About
Computer Science student at the University of North Texas (4.0 GPA) with a Certificate in Cybersecurity, focused on backend and systems engineering. Previously a Software Development Engineering Intern at GM Financial, where I diagnosed and resolved an API failure and contributed to a Preference Center built with Angular and ASP.NET services for unified account management features. I've also built backend services in C# and ASP.NET Core, designing REST APIs, JWT authentication, and secure backend systems for a role-based support platform. My projects focus on Python, C#, FastAPI, and .NET, exploring distributed systems, backend security practices, containerization with Docker, and scalable system architecture, with a growing interest in AI engineering. Interested in opportunities in backend engineering, distributed systems, or AI engineering. To see my projects: github.com/Aseel-Sh
