About Me

I'm a Computer Science student and aspiring C# .NET software developer, passionate about building robust backend solutions and creating meaningful software.

My focus is on backend development, working with APIs and databases, which excites me the most. I also know some basics of frontend development, giving me a well-rounded understanding of full-stack applications. In the future, I would like to specialize in System Design, as I enjoy tackling complex architectural challenges and building scalable, high-performing applications.

I'm passionate about writing clean, maintainable code and following best practices to ensure applications run efficiently and are built to last.
