Hi, I'm

Systems that Scale. Code that Lasts.

Developer focused on clean backend architectures and scalable solutions. Always learning, building, and improving systems that solve real-world challenges.

About Me

I’m a computer science student focused on backend development and problem-solving. With expertise in C++, data structures, algorithms, and modern web technologies, I build scalable backend systems and write clean, efficient code.

Whether architecting reliable APIs or solving complex algorithmic challenges, I enjoy turning ideas into practical, high-performance solutions.
