About Me

I'm a Computer Science student specializing in C# and .NET development, 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 have foundational frontend knowledge, giving me a well-rounded understanding of full-stack applications. In the long term, I aim to become a T-shaped developer with a focus on Cloud and DevOps, combining deep backend expertise with the ability to design, deploy, and operate scalable systems end-to-end.
